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. Functions to absorb materials through the root hairs and anchor the plant -provide storage for energy reserves






2. Responsible for the proliferationof antibodies after exposure to antigens






3. Conducts impulse slowly - allowing enough time for atrial contraction and for the ventricles to fill with blood






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






5. Excess interstitial fluid






6. Where blood flows through in arthropods






7. 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






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






9. The period of cardiac muscle relaxation during which blood drains into all four chambers






10. Branches into a series of arteries






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






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






14. Where exchange occurs in arthropods






15. Branch into microscopic capillaries






16. The period during which the ventricles contract






17. Serve protective functions -aka WBC






18. Cell-surface proteins that are macromolecules that are foreign to the host organism and trigger an immune response ex: ABO group and the Rh factor






19. The driving force of the circulatory system






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






21. Carry oxygenated blood from the lungs to the heart






22. Actively dividing - undifferentiated cells of a plant






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






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






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






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






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






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






29. Include arteries - veins - and capilleries






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






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






32. 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






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. Innervates the heart via the cervical and upper thoracic ganglia and causes an increase in the ehart rate






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






36. When hemoglobin bind to oxygen






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






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






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






40. Attracted to the injury site phagocytize antigenic material






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






42. Transport deoxygenated blood from the heart to the lungs






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






44. Physical barier against bacterial invasion






45. Cell fragments that lack nuclei and are involved in clot formation -involved in injury repair






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






47. 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






48. Supply plant cells with nutrients and remove waste products






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






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