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. Release of water from plants through stomata






2. Process that results in cell division to produce gametes






3. Epidermis - vascular - ground






4. Holds tissues together






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






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






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






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






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






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






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






12. Cells that form the outer surface of plants






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






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






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






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






17. Contracts or shortens making body parts move






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






19. 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






20. Chlorophyll containing plant cell organelle within which photosynthesis takes place






21. Organelle in which calcium levels are regulated






22. 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.






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






24. Organelle containing enzymes used in cell digestion






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






26. The basic structural and functional unit of all organisms






27. Produce progesterone and estrogens - in addition to eggs






28. Produces and stores nutrients through photosynthesis






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






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






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






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






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






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






35. 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






36. Largest organ in terms of surface area






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






38. Any cell in a multicellular organism except the gametes






39. Stores solid waste products






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






41. Protects the body and holds in heat






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






43. Attaches to bones and is responsible for voluntary movements






44. 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.






45. Connective - muscle - nervous - epithelial






46. 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






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






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






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






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