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






2. 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






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






4. Where exchange occurs in arthropods






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






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






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






8. Supply plant cells with nutrients and remove waste products






9. Attracted to the injury site phagocytize antigenic material






10. Serve protective functions -aka WBC






11. Fluid left after blood clotting






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






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






14. 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)






15. Transport deoxygenated blood from the heart to the lungs






16. Branch into arterioles






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






18. Phagocytic cells that filter the lymph - removing and destroying foreign particles and pathogens






19. Responsible for both of these immune mechanisms






20. 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






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






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






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






24. Primary organ of transport in the plant






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






26. Tissue involved in storage of nutrients and plant support






27. 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






28. Two upper chambers of the heart -thin walled






29. Systole and diastole - which together make a heartbeat






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






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






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






33. Actively dividing - undifferentiated cells of a plant






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






35. Excess interstitial fluid






36. Lying between the phloem and xylem - is a type of meristem called lateral meristem that provides for lateral growth of the stem by adding to the phloem or xylem






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






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






39. Include arteries - veins - and capilleries






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






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






42. When hemoglobin bind to oxygen






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






44. Where blood flows through in arthropods






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






46. 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






47. The period during which the ventricles contract






48. 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






49. Responsible for the proliferationof antibodies after exposure to antigens






50. Engulf and detroy foreign particles
