CSET Science: Subtest I Cell And Organismal Biology

Subjects : cset, science
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. Dense portion of the nucleus; contains RNA and is involved in protein synthesis






2. Supportive layer of tissue (sapwood or heartwood in trees) that carries water and nutrients up from the roots; dead cells






3. Organelle that 'packages' proteins to be secreted from the cell






4. Group of similarly constructed cells that perform the same function within a multicellular organism






5. A haploid reproductive cell that unites with another haploid reproductive cell to form a zygote






6. Detoxifies the blood - produces bile - and stores many vitamins and minerals






7. Organelle containing genetic material






8. Is actually a lymphoid organ in the neck or upper chest of all vertebrates. It is essential in the normal development of the immune system.






9. Produces digestive enzymes and the hormones insulin and glucagons






10. Cells that are able to differentiate into any type of cell in an organism






11. Produces hormones directly into the blood; pituitary gland - thyroid gland - adrenal glands - pancreas - ovaries - testes - thymus gland






12. Epidermis - vascular - ground






13. Plants with no phloem - xylem - roots - stems - or leaves; not as large or intricate as vascular plants






14. Covers organ surfaces (skin - airways - reproductive tract - inner lining of the digestive tract)






15. A doubled rod of condensed chromatin; contains DNA that carries genetic information.






16. Sweat glands and sebaceous glands






17. Attaches to bones and is responsible for voluntary movements






18. Brain and spinal cord






19. Microtubule within a cell's nucleus; joined to one of the poles during cell division






20. Useful for tearing and scratching






21. Holds tissues together






22. Produces and stores nutrients through photosynthesis






23. So named because it lacks striations. Involuntary muscle found along the walls of the digestive tract - bladder - arteries - and other internal organs.






24. Responsible for releasing several tropic hormones - which regulate the activity of other endocrine glands






25. Organisms with cells that lack membranous - structurally discrete organelles






26. In the life cycle of a plant or alga undergoing alternation of generations - a meiotically produced haploid cell that divides mitotically - generating a multicellular individual - the gametophyte - without fusing with another cell.






27. Responsible for defending the body against disease - causing agents; white blood cells (macrophages - B- cells and T- cells) - lymph nodes






28. Involuntary muscle that forms the contractile walls of the heart






29. Organism that harnesses light energy to produce organic materials from carbon dioxide and water






30. In plants - a form of undifferentiated embryonic cell; exists in areas of plant growth like the root and shoot tips






31. Process that results in cell division to produce gametes






32. One of the cells formed from a parents cell after mitosis






33. All of the nerves leading to and from the central nervous system






34. Pores underneath plant leaves used to exchange carbon dioxide and oxygen






35. Continuous sequence of growth (interphase) and division (mitosis) in a cell






36. Stage in which chromosomes are aligned in the center of the cell






37. Circulates through the vessels of the lymphatic system - which in turn assists the immune system.






38. Responsible for providing voluntary and involuntary movement; cardiac - skeletal - smooth






39. Discovered meiosis






40. Process that results in cell division






41. A cell that can differentiate into many different cell types






42. Last stage of mitosis - in which the cell membrane begins to pinch the cell in two - cytokinesis begins - and the nuclear membrane forms around the chromosomes






43. Organelle in which lipids and steroids are produced - carbohydrates and steroids are metabolized - and calcium concentration - drug detoxification - and attachment of cell membrane receptors are regulated.






44. Contracts or shortens making body parts move






45. Region of condense chromosome that looks pinched; where spindle fibers attach during meiosis and mitosis.






46. Third phase of mitosis and of meiosis I and II - in which the sister chromatids separate and move toward the poles of the spindle






47. Produce progesterone and estrogens - in addition to eggs






48. Nutrient conducting plant tissue; formed like small tubules; living cells






49. Membrane - bound and fluid filled organelle in plant of fungal cells; also found in some bacterial - protist - and animal cells






50. Organelle in which calcium levels are regulated
