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. Produce progesterone and estrogens - in addition to eggs






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






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






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






5. Connective - muscle - nervous - epithelial






6. Process that results in cell division to produce gametes






7. 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.






8. 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.






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






10. Organelle in which calcium levels are regulated






11. xylem and phloem; transport fluid and nutrients internally






12. Structure within a cell that is responsible for a specific function






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






14. Any cell in a multicellular organism except the gametes






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






16. 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






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






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






19. Produces and stores nutrients through photosynthesis






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






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






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






23. Organelle containing genetic material






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






25. Obsolete taxonomic group containing bacteria and cyanobacteria






26. Release of water from plants through stomata






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






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






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






30. Stores solid waste products






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






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






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






34. Your first line of defense against disease and helps regulate body temperature; skin - glands - hair - nails






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






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






37. Brain and spinal cord






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






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






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






41. Protects the body and holds in heat






42. Discovered meiosis






43. Produce testosterone and sperm






44. Organelle containing enzymes used in cell digestion






45. 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






46. Useful for tearing and scratching






47. Organelle in which proteins are synthesized






48. Cells that form the outer surface of plants






49. Strands of plant tissue containing xylem and phloem - sometimes surrounded by a fiber covering






50. Sweat glands and sebaceous glands
