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






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






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






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






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






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






7. Sweat glands and sebaceous glands






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






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






10. Stage of mitosis in which chromosomes condense into structures visible in a regular microscope






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






12. Organelle in which calcium levels are regulated






13. 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






14. Organelle in which proteins are synthesized






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






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






17. Produce progesterone and estrogens - in addition to eggs






18. Produces and stores nutrients through photosynthesis






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






20. Obsolete taxonomic group containing bacteria and cyanobacteria






21. Division of the cytoplasm during cell division






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






23. Discovered mitosis






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






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






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






27. Plant with specialized tissue for conducting water and nutrients






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






29. Made up of celluolose - protein - and lignin - and allows pressure in plant cells to increase without the cell bursting.






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






31. Located in the neck area. Releases thyroxin - which regulates the body's metabolic rate.






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






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






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






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






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






37. Organelle composed of microtubules within the nucleus that helps ensure that duplicated chromosomes are evenly distributed to the daughter cells






38. Organelle containing genetic material






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






40. Largest organ in terms of surface area






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






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






43. Epidermis - vascular - ground






44. Connections between plant cells that allow fluids and nutrients to be shared






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






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






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






48. Stores and releases bile






49. Useful for tearing and scratching






50. 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.
