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






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






3. Organelle in which proteins are synthesized






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






6. Produces and stores nutrients through photosynthesis






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






8. Stage of mitosis in which chromosomes condense into structures visible in a regular microscope






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






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






11. Process that results in cell division to produce gametes






12. Discovered meiosis






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






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






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






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






17. Organelle in which calcium levels are regulated






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






19. Sweat glands and sebaceous glands






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






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






22. Produce testosterone and sperm






23. Discovered mitosis






24. Protects the body and holds in heat






25. Stores and releases bile






26. Thin layer of plant tissue just below the bark which produces the xylem






27. Cells that form the outer surface of plants






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






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






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






31. Connective - muscle - nervous - epithelial






32. 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.






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






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






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






36. Any cell in a multicellular organism except the gametes






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






38. 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






39. Holds tissues together






40. 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.






41. Stores solid waste products






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






43. Organelle containing enzymes used in cell digestion






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






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






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






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






48. Produces digestive enzymes and the hormones insulin and glucagons






49. Plant with specialized tissue for conducting water and nutrients






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