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. Obsolete taxonomic group containing bacteria and cyanobacteria






2. 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






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






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






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






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






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






8. Protects the body and holds in heat






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






10. Produce progesterone and estrogens - in addition to eggs






11. 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.






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






13. Epidermis - vascular - ground






14. Organelle in which calcium levels are regulated






15. Produces and stores nutrients through photosynthesis






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






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






18. Organelle containing enzymes used in cell digestion






19. 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






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






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






22. Division of the cytoplasm during cell division






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






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






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






26. Makes up the brain - cranial nerves - spinal cord - and peripheral nervous system






27. Organelle containing genetic material






28. Process that results in cell division






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






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






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






32. Ability of a cell to differentiate into multiple different types of cells






33. Connections between plant cells that allow fluids and nutrients to be shared






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






35. Stores and releases bile






36. 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






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






38. Useful for tearing and scratching






39. Produce testosterone and sperm






40. Release of water from plants through stomata






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






42. Contracts or shortens making body parts move






43. Produces digestive enzymes and the hormones insulin and glucagons






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






45. Is actually a lymphoid organ in the neck or upper chest of all vertebrates. It is essential in the normal development of the immune system.






46. 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.






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






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






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






50. Any cell in a multicellular organism except the gametes
