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. Largest organ in terms of surface area






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






4. Located close to the kidneys. Responsible for releasing adrenaline - a hormone that produces the flight or fight response.






5. 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






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






7. Organelle in which calcium levels are regulated






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






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






10. Process that results in cell division






11. Any cell in a multicellular organism except the gametes






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






13. Plant with specialized tissue for conducting water and nutrients






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






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






16. 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






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






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






19. Circulates through the vessels of the lymphatic system - which in turn assists the immune system.






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






21. Cells that form the outer surface of plants






22. xylem and phloem; transport fluid and nutrients internally






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






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






25. Contracts or shortens making body parts move






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






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






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






29. 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.






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






31. Useful for tearing and scratching






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






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






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






35. Release of water from plants through stomata






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






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






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






39. Stores and releases bile






40. Produce progesterone and estrogens - in addition to eggs






41. Organelle containing genetic material






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






43. Protects the body and holds in heat






44. The basic structural and functional unit of all organisms






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






46. Produces digestive enzymes and the hormones insulin and glucagons






47. Discovered meiosis






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






49. Produces and stores nutrients through photosynthesis






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