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. Phloem - cambium - and xylem layers






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






3. Involves the production of antibodies and cell-mediated immunity






4. Involves cells that combat fungal and viral infection






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






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






7. Pumps oxygenated blood into systemic circulation (throughout the body)






8. Lined in passages - which filter and trap foreign particles






9. Transport deoxygenated blood from the heart to the lungs






10. Another antigen that may be present on the surface of red blood cells






11. Responsible for both of these immune mechanisms






12. Initiated by the body in response to physical damage and often accompanied by fever






13. Leukocytes involved in immune response and the production of antibodies (B cells) or cytolysis of infected cells (T cells)






14. Converts fibrinogen (another plasma protein) into fibrin






15. Primary organ of transport in the plant






16. The driving force of the circulatory system






17. (earthworm) uses a closed circulatory system to deliver materials to cells that are not in direct contact with the external environment






18. Branches into a series of arteries






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






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






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






22. Tissue involved in storage of nutrients and plant support






23. Valve on the left side of the heart that has two cusps






24. Located between the atria and ventricles on both sides of the heart - prevent backflow of blood into the atria






25. Supply plant cells with nutrients and remove waste products






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






27. Relatively thinly walled - inelastic vessels that conduct deoxygenated blood toward the heart






28. When hemoglobin bind to oxygen






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






30. Two lower chambers of the heart -extremely muscular






31. 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






32. Physical barier against bacterial invasion






33. Engulf and detroy foreign particles






34. Any liquid in a thin tube will rise becaUse of the surface tension of the liquid and interactions between the liquid and the tube






35. Secondary circulatory system distinct from the cardiovascular circulation - =vessels transport lymph to the cardiovascular system - thereby keeping fluid levels in the body constant






36. Modifies the rate of heart contraction






37. Where blood flows through in arthropods






38. Responsible for the proliferationof antibodies after exposure to antigens






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






40. Cells that are thick walled - often hollow cells located on the inside of the vascular bundle that carry water and minerals up the plant - and their thick walls give the plant its rigid support






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






42. Heterotrophic cells that generally consume other cells or food particles -movement of gases and nutrients is a ccomplished by simple diffusion within the cell






43. Smallest diameter of all three types of vessels; red blood cells must often travel through them single file






44. Composed of nonspecific and specific defense mechanisms






45. Secrete sweat - which contains an enzyme that attacks bacterial cell walls






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






47. Thin walled cells on the outside of the vascular bundle that transport nutrients down the stem -are living and include sieve tube cells and companion cells






48. Functions as the main heart by coordinated contractions in annelids






49. Include arteries - veins - and capilleries






50. Excess interstitial fluid
