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






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






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






4. Brain and spinal cord






5. Connective - muscle - nervous - epithelial






6. Plant with specialized tissue for conducting water and nutrients






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






8. Release of water from plants through stomata






9. Responsible for releasing several tropic hormones - which regulate the activity of other endocrine glands






10. Organism that harnesses light energy to produce organic materials from carbon dioxide and water






11. Division of the cytoplasm during cell division






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






13. Organelle in which proteins are synthesized






14. 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.






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






16. Attaches to bones and is responsible for voluntary movements






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






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






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






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






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






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






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






24. Process that results in cell division to produce gametes






25. Process that results in cell division






26. Organelle in which calcium levels are regulated






27. Produce progesterone and estrogens - in addition to eggs






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






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






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






31. Produce testosterone and sperm






32. 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






33. 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






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






35. Useful for tearing and scratching






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






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






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






39. Cells that form the outer surface of plants






40. 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






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






42. 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.






43. Organelle containing genetic material






44. Largest organ in terms of surface area






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






46. Protects the body and holds in heat






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






48. Epidermis - vascular - ground






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






50. Obsolete taxonomic group containing bacteria and cyanobacteria
