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






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






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






4. 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






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






6. Involves cells that combat fungal and viral infection






7. Serve protective functions -aka WBC






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






9. Responsible for both of these immune mechanisms






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






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






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






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






14. Blood is confined to blood vessel






15. Tissue involved in storage of nutrients and plant support






16. 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






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






18. Phloem - cambium - and xylem layers






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






20. Actively dividing - undifferentiated cells of a plant






21. 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)






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






23. Primary organ of transport in the plant






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






25. Systole and diastole - which together make a heartbeat






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






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






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






29. Have body walls that are two cells thick -all cels are direct contact with either the internal or external environments so there is no need for a specialized circulatory system






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






31. Carry oxygenated blood from the lungs to the heart






32. 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






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






34. Where exchange occurs in arthropods






35. Supply plant cells with nutrients and remove waste products






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






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






38. Released by injured cells - which causes blood vessels to dilate - thereby increasing blood flow to the damaged region






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






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






41. 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






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






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






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






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






47. Modifies the rate of heart contraction






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






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






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