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. Involves the production of antibodies and cell-mediated immunity






2. Tissue involved in storage of nutrients and plant support






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






4. Liquid portion of the blood -aqueous mixture of nutrients - salts - respiratory gases - wastes - hormones - and blood proteins -components are erythrocytes - leukocytes - and platelets






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






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






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






8. Include arteries - veins - and capilleries






9. Composed of nonspecific and specific defense mechanisms






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






11. Severe anemia for the fetus caused by Rh+ fetus






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






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






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






15. Actively dividing - undifferentiated cells of a plant






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






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






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






19. 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






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






21. Engulf and detroy foreign particles






22. Responsible for the proliferationof antibodies after exposure to antigens






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






24. Branch into microscopic capillaries






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






26. Serve protective functions -aka WBC






27. 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






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






29. Blood is confined to blood vessel






30. Cardiac muscle contracts rhythmically without stimulation from the nervous system - producing impulses that spread through its internal conducting system






31. 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






32. Branches into a series of arteries






33. Primary organ of transport in the plant






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






35. Physical barier against bacterial invasion






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






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






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






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






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






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






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






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






44. 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






45. Universal donor since it will not elicit a response from the recipient's immune system because it does not possess any surface antigens






46. Where blood flows through in arthropods






47. Fetal red blood cells (which will have the Rh factor) enter maternal circulation during birth which cause the anti-Rh antibodies she produced when sensitized by the first birth may cross the placenta and destroy fetal red blood cells






48. Two upper chambers of the heart -thin walled






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






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