PCAT Biology Vascular Systems In Animals And Plants

Subjects : pcat, biology
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Blood is confined to blood vessel






2. Involves cells that combat fungal and viral infection






3. Leukocytes that phagocytize foreign matter and organisms such as bacteria






4. Have open circulatory systems in which blood (interstitial fluid) is in direct contact with the body tissues -blood is circulated primarily by body movements






5. Responsible for both of these immune mechanisms






6. Engulf and detroy foreign particles






7. Thick-walled - muscular - elastic vessels that transport oxygenated blood away from the heart






8. Lying between the phloem and xylem - is a type of meristem called lateral meristem that provides for lateral growth of the stem by adding to the phloem or xylem






9. When hemoglobin bind to oxygen






10. Specialized of the root epidermis with thin-walled projections increase the surface area for absorption of water and minerals from the soil






11. Converge into venules and eventually into veins - leading deoxygenated blood back toward the heart






12. Two layers thick and are the actively dividing - undifferentiated cells that give rise to xylem and phloem cell layers; as they divide - the cells near the phloem differentiate into phloem cells - and the cells near the xylem differentiate into xylem






13. Where exchange occurs in arthropods






14. Branches into a series of arteries






15. Leukocytes that migrate from the blood to tissue - where they mature into stationary cells






16. Supply plant cells with nutrients and remove waste products






17. Produced by cells under viral attack and diffuse to other cells - where they help prevent the spread of the virus






18. Composed of nonspecific and specific defense mechanisms






19. Skin - mucous-coated epithelia - macrophages - inflammatory - interferons






20. Blood transports nutrients and O2 to tissue and wastes and CO2 from tissue -transport of gases - transport of nutrients and wste - and clotting






21. Responsible for generating the force that propels systematic circulation and pumps against a higher resistance






22. Innervates the heart via the vagus nerve and causes a decrease in the heart rate






23. Oxygen carrying components of blood -formed from stem cells in the bone marrow where they lose their nuclei - mitochodnria - and membranous organelles






24. Run up and down the stem at the center and contains xylem - phloem - and cambium cells






25. Swellins along lyph vessels containing phagocytic cells that filter the lymph - removing and destroying foreign particles and pathogens






26. Composed of muscular - four-chambered heart - a network of blood vessels - and the blood itself






27. Where blood flows through in arthropods






28. Exchange of gases - nutrients - and cellular waste products occurs via diffusion across this






29. Tissue involved in storage of nutrients and plant support






30. Phloem - cambium - and xylem layers






31. Have body walls that are two cells thick -all cels are direct contact with either the internal or external environments so there is no need for a specialized circulatory system






32. Used to lower the immune response to transplants and decrease the likelihood of rejection






33. Carries impuls of AV node which branches into the right and left bundle branches - and through the Purkinje fibers in the walls of ventircles - generating a strong contraction






34. Carry oxygenated blood from the lungs to the heart






35. Water entering the root hairs exerts a pressure that pushes water up the stem






36. Attracted to the injury site phagocytize antigenic material






37. In annelids - five pairs of vessels that connect the dorsal vessel to the ventral vessel and function as additional pumps






38. As water evaporates from the leaves of plants - a vacuum is created pulls water up the stem






39. Outer layer of xylem that is alive






40. An individual is injected witha weakened - inactive - or related form of a particular antigen - which stimulates the immune system to produce specific antibodies against it






41. The period during which the ventricles contract






42. Responsible for the proliferationof antibodies after exposure to antigens






43. Transport deoxygenated blood from the heart to the lungs






44. Located at the tips of roots and stems where division leads to increase in length






45. A small mass of specialized tissue located in the wall of the right atrium regulates/originates an ordinary cardiac contraction -spreads impulses through both atria - stimulating them to contract simultaneously






46. Prevent extensive blood loss while the damaged vessel heals itself






47. Modifies the rate of heart contraction






48. Valve on the right side of the heart has three cusps






49. Branch into microscopic capillaries






50. Coat the damaged area and trap blood cells to form a clot
