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. 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






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






3. Attracted to the injury site phagocytize antigenic material






4. Supply plant cells with nutrients and remove waste products






5. Converts fibrinogen (another plasma protein) into fibrin






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






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






8. Branch into microscopic capillaries






9. Responsible for both of these immune mechanisms






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






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






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






13. Where blood flows through in arthropods






14. Actively dividing - undifferentiated cells of a plant






15. Phagocytic cells that filter the lymph - removing and destroying foreign particles and pathogens






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






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






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






19. The production of antibodies during an immune response -can be conferred by vaccination






20. Tissue involved in storage of nutrients and plant support






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






22. 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






23. Composed of nonspecific and specific defense mechanisms






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






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






26. Involves cells that combat fungal and viral infection






27. Have three cusps and are located between the left ventricle and the aorta and between the right ventricle and the pumonary artery (the pulmonic valve)






28. Branch into arterioles






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






30. Universal recipient as it has neither anti-A nor anti-B antibodies






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. Pumps deoxygenated blood into pulmonary circulation (toward the lungs)






33. Include arteries - veins - and capilleries






34. Exerts hormonal control via epinepherine (adrenaline) secretion - which causes an increase in heart rate






35. Responsible for the proliferationof antibodies after exposure to antigens






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






37. Fraction of the blood containing a wide variety of antibodies - that can be used to confer temporary protection against hepatitis and other diseases by passive immunity






38. Involves the transfer of antibodies produced by another individual or organism -acquired either passively or by injection






39. Epidermis (outer-bark) - cortex - phloem - cambium - xylem - and pith






40. The period during which the ventricles contract






41. Two upper chambers of the heart -thin walled






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






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






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






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






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






47. Branches into a series of arteries






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






49. When platelets come into contact with the exposed collagen of a damaged vessel - they release a chemical chemical that causes neighboring platelets to adherer to one another






50. Carry oxygenated blood from the lungs to the heart
