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






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






3. The basic structural and functional unit of all organisms






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






5. Organelle in which proteins are synthesized






6. Division of the cytoplasm during cell division






7. Discovered mitosis






8. 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.






9. Produce testosterone and sperm






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






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






12. Produces and stores nutrients through photosynthesis






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






14. 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






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






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






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






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






19. Located close to the kidneys. Responsible for releasing adrenaline - a hormone that produces the flight or fight response.






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






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






22. Discovered meiosis






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






24. Obsolete taxonomic group containing bacteria and cyanobacteria






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






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






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






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






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






30. Largest organ in terms of surface area






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






32. Brain and spinal cord






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






34. Useful for tearing and scratching






35. 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






36. Connective - muscle - nervous - epithelial






37. Produce progesterone and estrogens - in addition to eggs






38. Contracts or shortens making body parts move






39. Protects the body and holds in heat






40. Holds tissues together






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






42. Attaches to bones and is responsible for voluntary movements






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






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






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






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






47. Organisms with cells that have a membrane - bound nucleus and other well - structured organelles






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






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






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