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. Brain and spinal cord






2. Useful for tearing and scratching






3. Process that results in cell division






4. Attaches to bones and is responsible for voluntary movements






5. Discovered meiosis






6. Your first line of defense against disease and helps regulate body temperature; skin - glands - hair - nails






7. xylem and phloem; transport fluid and nutrients internally






8. Ability of a cell to differentiate into multiple different types of cells






9. Dense portion of the nucleus; contains RNA and is involved in protein synthesis






10. 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






11. Stores and releases bile






12. Cells that form the outer surface of plants






13. The process by which a cell becomes specialized for a specific structure or function






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






15. Responsible for the breakdown and absorption of food and the removal of solid waste; include the alimentary canal (mouth - esophagus - stomach - small intestine - large intestine - colon/ rectum) and the accessory organs (liver - pancreas - gall blad






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






17. Organelle in which proteins are synthesized






18. An extensive membrane network of cisternae (sac - like structures) held together by the cytoskeleton that encloses the cisternal space (or lumen) from the cytosol and is continuous with the perinuclear space. Three types: RER - SER - SR






19. Thin layer of plant tissue just below the bark which produces the xylem






20. Epidermis - vascular - ground






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






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






23. 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.






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






25. Protects the body and holds in heat






26. Include macrophages - B- cells - and T- cells






27. Responsible for extracting water and essential vitamins from the digested food






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






29. Tiny nodules found all over the body. They contain a colorless fluid called lymph.






30. Makes up the brain - cranial nerves - spinal cord - and peripheral nervous system






31. A complex polymer that fills the spaces in the cell wall - conferring mechanical strength to the cell wall and the plant as a whole.






32. One of two identical 'sister' parts of a duplicated chromosome






33. Strands of plant tissue containing xylem and phloem - sometimes surrounded by a fiber covering






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






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






36. Responsible for storing food and initiating the digestion of proteins






37. Eukaryotic organism that is not an animal - a plant - or a fungus.






38. Responsible for transporting materials throughout the body: heart - blood (red - white - platelets) - blood vessels (arteries - vein - capillaries)






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






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






41. 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.






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






43. Produce progesterone and estrogens - in addition to eggs






44. Organelle in eukaryotic cells that produces chemical energy; have their own DNA and may have evolved from a symbiotic relationship between a primitive eukaryotic organism and a primitive bacteria






45. Responsible for digesting and absorbing the extracted vital nutrients from food






46. Produces digestive enzymes and the hormones insulin and glucagons






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






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






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






50. Small sac within a cell formed by pinching of some membrane; can contain waste - products the cell is taking in - and secretions the cell is exporting
