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. Produce testosterone and sperm






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






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






4. Protects the body and holds in heat






5. Obsolete taxonomic group containing bacteria and cyanobacteria






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






7. Produces digestive enzymes and the hormones insulin and glucagons






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






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






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






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






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






13. Organelle containing genetic material






14. Sweat glands and sebaceous glands






15. Organelle containing enzymes used in cell digestion






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






17. 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






18. Small sac within a cell formed by pinching of some membrane; can contain waste - products the cell is taking in - and secretions the cell is exporting






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






20. Process that results in cell division to produce gametes






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






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






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






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






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






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






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






28. 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.






29. Organelle in which proteins are synthesized






30. Responsible for the collection - transference - and the processing of external and internal information throughout the body; central nervous system - peripheral nervous system






31. Contracts or shortens making body parts move






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






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






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






35. Discovered meiosis






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






37. Discovered mitosis






38. Any cell in a multicellular organism except the gametes






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






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






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






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






43. 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






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. Produces and stores nutrients through photosynthesis






46. Release of water from plants through stomata






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






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






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