Question: What do seedless vascular plants and bryophytes have in common? What features do seedless vascular plants and bryophytes have in common? What features differ between the two? Thank you so much for any help :)

Answer: In addition to the above answer, and the most likely answer is that they both reproduce via spores. But bryophytes can also reproduce using asexual reproduction i.e. fragmentation and gemmae cups so be careful and dont just say they have the "same reproduction".

They secrete acids that keep the fungal partner from growing too quickly. C. They contain endosymbiotic fungi. D. They provide organic nutrients to fungal partners. E. They are digested by fungal enzymes while still alive.

Answer: D. They provide organic nutrients to fungal partners.

Question: How do vasoconstrictors relieve a vascular headache? A vascular headache is a headache where blood vessel swelling or disturbance causes the pain. Vasoconstrictors are supposed to help, but I'm not sure why or how.

Answer: They narrow the blood vessels, slowing the blood flow.

Question: How is a vascular plant like a factory? How is a vascular plant like a factory? I have science homework on vascular plants. Science is my weak spot and I do not understand the concept on this lesson. Please help.

Answer: Different part of the plant do different things. The roots take water and nutrients from the soil and transport them up to the leaves. The leaves create sugars and foods from the sun (through photosynthesis) and the plant moves those down to the roots. Altogether, it forms a living "machine" that produces growth and fruits (seeds).

Question: How do I improve my cardio vascular fitness/endurance level? Any supplement can help? I know that exercise can improve cardio vascular fitness level but is there any supplement / medication that can raise it?

Answer: any supplement/medication that raises your cardio rate is BAD BAD BAD. it would stress your system unnaturally. Stick to the sweat and huff method. Run,jog, etc.

Question: Do vascular problems in your leg have an impact on migraene headaches? I have severe Migraene hadaches for several days in the row. Now, I also have vascular problems in my left leg. Is there an research study of the these two symptoms which tricker the other?

Answer: This is the BEST Headache information. Make the connection! Being a nurse with over 25 years experience, I have seen a lot of people with various illnesses. Many allergic reaction are indeed caused from foods HOWEVER...many more are caused from chemicals and fragranced products as well as VOC's in homes, schools and workplace. This is a growing problem and many people are not even aware that it exists as more and more chemicals are being introduced and used on a daily basis. Many people believe that because something smells good and it is on a store shelf that it is tested, approved and safe for use. Think again ! We are now seeing more and more children and adults with Chronic Headaches, Sinusitis, Migraines, Chronic Sinus Infections, Asthma, Allergies, Hives, Eczema, sinus / respiratory illnesses and Hormone related disorders. I can not emphasize how important it is to educate yourself about MULTIPLE CHEMICAL SENSITIVITY (MCS) and the harm you may be doing to your health by using chemicals and fragranced products. If you or a loved one has symptoms of or suffers from Asthma, Allergies, Autism, chronic headaches, reproductive problems, Migraines, Chronic Fatigue Syndrome, Lupus or Fibromyalgia, you need to read further and learn about the signs and symptoms of MCS - Multiple Chemical Sensitivity. Most doctors will not inform you about this because patients as a whole like to walk out of a doctors office with a prescription for some magical medicine and they do not want to be told that their expensive new perfume or newly installed carpet may be the culprit. So, the doctor will give you medications and many of these meds either do not work or cause other health problems. Chemicals and fragranced products are often the root of many disorders and illnesses when it comes to your health. Many of the below mentioned items are common triggers to sinus, asthma, itching, headaches, Migraines and allergy problems amongst other health issues. Get rid of them and your immune and respiratory system will thank you and you will breathe easier. And, it is not only personal body or cleaning products causing havoc on your health….many people become ill after wearing brand new clothing, dry-cleaned clothes, installing new carpet, painting, buying a new mattress or after home renovations because of the Flame Retardants, Antimony, Benzenes, Formaldehydes, etc. used in these products. So the answer is NO, you are not imagining that 2 weeks after your home, office or classroom got renovated you started to become ill, get dizzy or have headaches. This is happening more and more these days and adults as well as children are becoming sicker and sicker. Unfortunately, too many doctors compound the problem by prescribing chemical medications to try to alleviate the symptoms of an already chemical overloaded body and they rarely tell the patient to eliminate the chemical offenders. How many times have I seen people in the grocery store with Bounce, Glade Plug-Ins and Febreeze in their shopping cart along with a bottle of Benadryl , Migraine Excedrin and a box of Allergy Tablets ? Why don't they make the connection? Keep in mind that your skin is the largest organ of your body and what you put on your skin gets absorbed into your body. Then ... well... then it has to be filtered by your organs which are already working real hard. BIG NO-NO's ---- I would SERIOUSLY recommend removing all of the below from your living / working area. No Bounce or dryer sheets - these are VERY toxic No Febreeze - your pets will even thank you for this No Glade Plug-ins - VERY toxic No Scented candles No Scented Dish Detergents No Fragranced Products on Body, Hair or Clothing No Smoke No Newspapers and Magazines - The ink is a huge irritant. No Dander No Sprays No Sharpies (marker pens) New Cartpeting, mattresses, paint, contain toxins that can trigger severe respiratory disorders as well as headaches and Asthma flare-ups. And remember, it is NOT the smell it is the Chemicals that make up the smell. So, even if something is "Fragrance Free" these products often mask the smell with another chemical ! There are plenty of safe healthy products out there that work well and do not have added chemical fragrances. More and more workplaces & schools are implementing Fragrance Free policies and creating "Fragrance Free Zones"… why do you think this is? Make the connection, your lungs , immune system and your general health will thank you.

Question: What would happen if a plant's vascular system contained only xylem? A. The vascular system would still function normally. B. The vascular system would be made up mostly of photosynthesizing cells. C. The vascular system would be unable to transport water and dissolved mineral nutrients. D. The vascular system would be unable to transport the products of photosynthesis.

Answer: D. The vascular system would be unable to transport the products of photosynthesis. Due to a lack of phloem.

Question: What is the principal distinguishing feature of vascular plants? 1) What is the principal distinguishing feature of vascular plants? 2) Why are ferns and flowering plants placed in different phyla?

Answer: Vascular plants can grow taller since they do not have to retain close contact of all parts with a source of moisture. Vascular conduction provides water to the plant parts that passive diffusion is insufficient to supply. Ferns release single celled spores and gametes between the phases of the alternation of generations. These spores survive moderately well to spread new plants but gametes provide for little cross fertilization since they are severely restricted in range and dependence on water. Both conifers and flowering plants retain the micro-spore until it develops into a gametophyte. The entire male micro-gametophyte is released as the pollen. This means it can survive and travel well and prevents the need for the gametes to swim. The pollen that finds the ovule delivers the gametes via the pollen tube directly to the ova. Flowering plant gametes do not have flagella like the ferns. In flowering plants the female mega-spore is the ovule or female gametophyte inside the ovary. Once the ovule is fertilized seeds form and the ovary matures into the seed bearing fruit. In both conifers and flowering plants the travel is carried out by multicellular pollen, the microgametophyte, and seeds, the juvenile spermatophyte for better cross fertilization and ability to be spread.

Question: How do I become a Vascular Ultrasound Technologist? I am interested in Vascular Ultrasound Technologist...From what I've gathered so far there is formal training offered through a two year associate degree? Is that a AA degree? If not do I need to obtain a general AA degree first? and Then a vascular Ultrasound Technologist two year associate degree?

Answer: Yes, you can get your training as a vascular tech through a two-year degree. What you'll end up with is an AAS (associate in applied sciences). Though you don't need a general AA first, you will probably need to take some classes (like anatomy/physiology, English, medical terminology, etc.) before you even apply to the program. The program at my school doesn't require volunteer work, an interview, or letters of recommendation, but some programs require some or all of these things. Be sure to check carefully all the requirements of the program that interests you.

Question: What naturally patches up tears in your vascular system? What substance naturally patches up tears that cause bleeding in your vascular system? Is it cholesterol? Please, no speeches on how cholesterol is bad for you.

Answer: Platelets, and they use fibrin and other cells to form a band-aid.

Question: How does this compare to the number of vascular bundles in the stem? Examine the photograph of a prepared slide of the root cross section. Notice that the section is circular in outline since it was cut across the root.  The vascular tissue of the root is concentrated in a single vascular bundle or stele in the center of the root. How does this compare to the number of vascular bundles in the stem?

Answer: There are more vascular bundles in the stem because the stem has more transportation to do. The roots are only moving water and nutrients to the stem, but the stem has to move the stuff to many different leaves and back down to the root. With so much responsibility, it makes since that there are more vascular bundles in the stem to help things move swifter.

Question: What are the vascular tissues in animals? Is Blood Smear a vascular tissue? Could you give me other examples, and please provide a short description, its location and function. Thanks in advance.

Answer: no a blood smear is when you put a drop of blood on a microscope slide to check for something like parasites In animals the vascular tissue is in the veins and areries. Part of the circular system. The circulatory system is an organ system that passes nutrients (such as amino acids and electrolytes), gases, hormones, blood cells, etc. to and from cells in the body to help fight diseases and help stabilize body temperature and pH to maintain homeostasis. This system may be seen strictly as a blood distribution network, but some consider the circulatory system as composed of the cardiovascular system, which distributes blood, and the lymphatic system, which distributes lymph. While humans, as well as other vertebrates, have a closed cardiovascular system (meaning that the blood never leaves the network of arteries, veins and capillaries), some invertebrate groups have an open cardiovascular system. The most primitive animal phyla lack circulatory system. The lymphatic system, on the other hand, is an open system. The main components of the human circulatory system are the heart, the blood, and the blood vessels. The circulatory system includes: the pulmonary circulation, a "loop" through the lungs where blood is oxygenated; and the systemic circulation, a "loop" through the rest of the body to provide oxygenated blood. An average adult contains five to six quarts (roughly 4.7 to 5.7 liters) of blood, which consists of plasma, red blood cells, white blood cells, and platelets. Also, the digestive system works with the circulatory system to provide the nutrients the system needs to keep the heart pumping.

Question: What is the definition of a vascular tissue? ( lot more questions inside but 10 points to whoever answers all) What are the two types of vascular tissue? How are the types of tissue similar? How are they structurally different? What does each type of vascular tissue transport? How does each tissue transport materials and in what direction?

Answer: Vascular tissue is a complex tissue found in vascular plants, meaning that it is composed of more than one cell type. The primary components of vascular tissue are the xylem and phloem. These two tissues transport fluid and nutrients internally. There are also two meristems associated with vascular tissue: the vascular cambium and the cork cambium. All the vascular tissues within a particular plant together constitute the vascular tissue system of that plant. The cells in differentiated vascular tissue are typically long and slender. Since the xylem and phloem function in the conduction of water, minerals, and nutrients throughout the plant, it is not surprising that their form should be similar to pipes. The individual cells of phloem are connected end-to-end, just as the sections of a pipe might be. As the plant grows, new vascular tissue differentiates in the growing tips of the plant. The new tissue is aligned with existing vascular tissue, maintaining its connection throughout the plant. The vascular tissue in plants is arranged in long, discrete strands called vascular bundles. These bundles include both xylem and phloem, as well as supporting and protective cells. In stems and roots, the xylem typically lies closer to the interior of the stem with phloem towards the exterior of the stem. In the stems of some Asteriidae dicots, there may be phloem located inwardly from the xylem as well. Between the xylem and phloem is a meristem called the vascular cambium. This tissue divides off cells that will be become additional xylem and phloem. This growth increases the girth of the plant, rather than its length. As long as the vascular cambium continues to produce new cells, the plant will continue to grow more stout. In trees and other plants that develop wood, the vascular cambium allows the expansion of vascular tissue that produces woody growth. Because this growth ruptures the epidermis of the stem, woody plants also have a cork cambium that develops among the phloem. The cork cambium gives rise to thickened cork cells to protect the surface of the plant and reduce water loss. Both the production of wood and the production of cork are forms of secondary growth. In leaves, the vascular bundles are located among the spongy mesophyll. The xylem is oriented toward the adaxial surface of the leaf (usually the upper side), and phloem is oriented toward the abaxial surface of the leaf. This is why aphids are typically found on the underside of the leaves rather than on the top, since the phloem transports sugars manufactured by the plant and they are closer to the lower surface In vascular plants, xylem is one of the two types of transport tissue, phloem being the other. The word "xylem" is derived from classical Greek ξυλον (xylon), "wood", and indeed the best known xylem tissue is wood, though it is found throughout the plant. Its basic function is to transport water to know more aboutxylem go with pictures go to http://en.wikipedia.org/wiki/Xylem In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), particularly sucrose, a sugar, to all parts of the plant where needed. In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Greek word φλόος (phloos) "bark". The phloem is mainly concerned with the transport of soluble organic material made during photosynthesis. This is called translocation. to now more about phloem go to http://en.wikipedia.org/wiki/Phloem hope this helped you :)

Question: How much schooling do you need to become a Cardio Vascular Surgeon? I'm thinking about either becoming a Physician Assistant or a Cardio Vascular surgeon, but I'm unsure on how much schooling you need to become a surgeon. I know you have to go to Pre Med School, then Medical school but is there anymore schooling after that?

Answer: You'll need a bachelors degree (college, 2-4 years). Then medical school (4 years), then residency. You'll have a 1 year internship in general surgery, then 4-5 more years in CT (cardiothoracic) surgery, depending on how specialized you want. The part after med school is residency, and you do get paid for it. Physician's assistant is a lot less school, but CT surgeons make 5-7 times the amount of money. Best of luck.

Answer: xylem and phloem

Question: How can i plan a quick biology essay having to do with vascular plants and water movement? (need to include these) a) Explain the mechanism of water movement through vascular plants during transpiration. b) Explain how gas exchanges affect transpiration c) Describe two adaptations that affect the rate of transpiration in desert plants.

Answer: You need to discuss capillary action and how that relates to the physical structure of a plant's vesicles. How the xylem's xylem's diameter is small enough for the water to move by capillary action. Capillary action http://www.uni.edu/~iowawet/H2OPropertie… Transpiration pull and root pressure moves water. http://plantphys.info/plant_physiology/t… Transpiration and properties of water http://generalhorticulture.tamu.edu/lect… Animation of water & sucrose movement in xylem & phloem http://academic.kellogg.cc.mi.us/herbran… Letting CO2 in while water evaporates also promotes photosynthesis. If the plant's soil is dry and the weather warm the plant will close the stomata to conserve water. Now the plant also lacks CO2. Both CO2 and water are essential for photosynthesis to proceed so even with plenty of sunlight the plant cannot photosynthesize. To separate the collection of CO2 from the escape of H2O some plants have additional steps. The answer is to separate the functions of saving water and getting CO2 by using the C4 process. The physical separation costs a bit more in energy but conserves water very well so C4 works best in tropical climates with intense sunlight. C4 adds a step that grabs and stores the CO2 in a separate space from the pore. This lets CO2 diffuse into the open pore faster so the opening can be closed sooner costing the plant less water loss. This is what requires the extra energy, moving the CO2 faster so more can diffuse down the gradient the plant creates. Plants have three options in gas exchange controls for photosynthesis: C3, C4, & CAM 1 - C3 plants are slow because they use rubisco & natural rates of diffusion of both H2O & CO2 gases. 2 - C4 plants speed up the diffusion rate of CO2 by driving it into storage at a slight cost. This allows the stomata to close sooner so less H2O is lost. 3 - CAM changes how the stomate opening is timed so the gases are exchanged at night when it is cooler, and the CO2 is sequestered by the C4 pathway. Time delay plus physical CO2 storage. CAM plants respond to internal CO2 levels. Low CO2 storage causes the stomata to open. http://www.biologie.uni-hamburg.de/b-onl… Gas is exchanged at the leaf pores. Leaves have a waxy cuticle to prevent water loss except through portals designed for gas exchanges: stomata. The stomata are fully regulated to control open/closing. Even their density on the leaf effects the rate of transpiration. Up to a point the more pores the more the plant can transpire. After a point adding more pores does not increase the rate of transpiration. Reducing the number or shifting where they are placed can reduce the rate however. Stomata are located behind sheltering spines or hairs to slow the movement of air over the pores. Number of stomata/area and surface texture - Surface area is a factor. Large surfaces have a larger boundary layer. This is a quieter layer of air as it touches the photosynthetic surface of the leaf (or stem in cacti). The presence of hairs, spines or texture can hold a deeper boundary layer of air to slow transpiration further.
