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. 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.






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






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






4. Organelle in which proteins are synthesized






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






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






7. 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






8. 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






9. Sweat glands and sebaceous glands






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






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






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






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






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






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






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






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






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






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






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






21. Produces and stores nutrients through photosynthesis






22. Organelle in which calcium levels are regulated






23. Attaches to bones and is responsible for voluntary movements






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






25. Holds tissues together






26. Process that results in cell division to produce gametes






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






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






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






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






31. Brain and spinal cord






32. Useful for tearing and scratching






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






34. 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.






35. Produce progesterone and estrogens - in addition to eggs






36. Process that results in cell division






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






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






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






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






41. Any cell in a multicellular organism except the gametes






42. Organelle containing genetic material






43. 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.






44. Organelle containing enzymes used in cell digestion






45. Division of the cytoplasm during cell division






46. 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






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






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






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






50. Discovered meiosis
