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. Severe anemia for the fetus caused by Rh+ fetus






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






4. Outer layer of xylem that is alive






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






6. Two lower chambers of the heart -extremely muscular






7. Involves cells that combat fungal and viral infection






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






9. Excess interstitial fluid






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






11. Converts fibrinogen (another plasma protein) into fibrin






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






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






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






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






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






17. Primary organ of transport in the plant






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






19. 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






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






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






22. An individual is injected witha weakened - inactive - or related form of a particular antigen - which stimulates the immune system to produce specific antibodies against it






23. Supply plant cells with nutrients and remove waste products






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






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






26. 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






27. Fluid left after blood clotting






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






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






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






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






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






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






35. 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)






36. Engulf and detroy foreign particles






37. Where blood flows through in arthropods






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






39. Physical barier against bacterial invasion






40. The period during which the ventricles contract






41. 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






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






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






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






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






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






47. 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






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






49. 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)






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