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. Inappropriate response to certain foods and pollen that cause the body to form antibodies and release histamine






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






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






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






5. Responsible for both of these immune mechanisms






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






7. 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






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






9. Branches into a series of arteries






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






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






12. Excess interstitial fluid






13. Branch into arterioles






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






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






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






17. 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






18. Composed of nonspecific and specific defense mechanisms






19. Supply plant cells with nutrients and remove waste products






20. 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






21. Transport deoxygenated blood from the heart to the lungs






22. The period during which the ventricles contract






23. Modifies the rate of heart contraction






24. 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






25. Carry oxygenated blood from the lungs to the heart






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






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






28. Involves cells that combat fungal and viral infection






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






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






31. Branch into microscopic capillaries






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






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






34. Primary organ of transport in the plant






35. Responsible for the proliferationof antibodies after exposure to antigens






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






37. Two upper chambers of the heart -thin walled






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






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






40. When hemoglobin bind to oxygen






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






42. Tissue involved in storage of nutrients and plant support






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






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






45. Defined as the total volume of blood the left ventricle pumps out per minute = heart rate (number of BPM) x stroke volume (volume of blood pumped out of the left ventricle per contraction)






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






47. 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






48. 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






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






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