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. Organelle composed of microtubules within the nucleus that helps ensure that duplicated chromosomes are evenly distributed to the daughter cells






2. 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






3. 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






4. 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






5. Discovered meiosis






6. Useful for tearing and scratching






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






8. Produces and stores nutrients through photosynthesis






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






10. Organelle containing enzymes used in cell digestion






11. Holds tissues together






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






13. Produces digestive enzymes and the hormones insulin and glucagons






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






15. Connective - muscle - nervous - epithelial






16. 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.






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






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






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






22. Process that results in cell division






23. Organelle in which proteins are synthesized






24. Attaches to bones and is responsible for voluntary movements






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






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






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






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






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






30. Contracts or shortens making body parts move






31. Sweat glands and sebaceous glands






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






33. 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.






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






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






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






37. Discovered mitosis






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






39. Stores and releases bile






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






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






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






43. Release of water from plants through stomata






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






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






46. Organelle in which calcium levels are regulated






47. Obsolete taxonomic group containing bacteria and cyanobacteria






48. Cells that form the outer surface of plants






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






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