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






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






3. Organelle containing enzymes used in cell digestion






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






5. 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






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






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






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






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






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






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






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






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






14. 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.






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






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






18. Largest organ in terms of surface area






19. Attaches to bones and is responsible for voluntary movements






20. Stores solid waste products






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






22. Discovered mitosis






23. Cells that form the outer surface of plants






24. xylem and phloem; transport fluid and nutrients internally






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






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






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






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






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






30. 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.






31. Structure within a cell that is responsible for a specific function






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. Produce progesterone and estrogens - in addition to eggs






34. Organelle in which calcium levels are regulated






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






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






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






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






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






40. Stores and releases bile






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






42. Organelles critical to protein synthesis found in the cytoplasm - joined to the endoplasmic reticulum - and within the mitochondria






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






44. 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






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






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






47. Release of water from plants through stomata






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






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






50. Produces and stores nutrients through photosynthesis
