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. Connective - muscle - nervous - epithelial






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






3. Produces and stores nutrients through photosynthesis






4. Discovered mitosis






5. Protects the body and holds in heat






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






7. Holds tissues together






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






9. Brain and spinal cord






10. Cells that form the outer surface of plants






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






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






13. Sweat glands and sebaceous glands






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






15. 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.






16. Discovered meiosis






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






18. Contracts or shortens making body parts move






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






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






21. Division of the cytoplasm during cell division






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






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






24. Largest organ in terms of surface area






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






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






27. Process that results in cell division to produce gametes






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






29. The gamete - producing individual or phase in the life cycle of a plant having alternation of generations






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






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






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






33. Release of water from plants through stomata






34. Organelle containing enzymes used in cell digestion






35. Produce testosterone and sperm






36. Produce progesterone and estrogens - in addition to eggs






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






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






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






40. Stores and releases bile






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






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






43. The basic structural and functional unit of all organisms






44. Obsolete taxonomic group containing bacteria and cyanobacteria






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






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






47. 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






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






49. Any cell in a multicellular organism except the gametes






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