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






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. Protects the body and holds in heat






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






5. Attaches to bones and is responsible for voluntary movements






6. Cells that form the outer surface of plants






7. Plant with specialized tissue for conducting water and nutrients






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






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






10. 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.






11. Organelle in which calcium levels are regulated






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






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






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






15. 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






16. 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






17. Organelle in which proteins are synthesized






18. Connective - muscle - nervous - epithelial






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






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






21. One of two identical 'sister' parts of a duplicated chromosome






22. 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.






23. 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.






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






25. Produce progesterone and estrogens - in addition to eggs






26. Process that results in cell division to produce gametes






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






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






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






30. Stores solid waste products






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






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






33. Release of water from plants through stomata






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






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






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






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






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






39. Contracts or shortens making body parts move






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






41. Produce testosterone and sperm






42. 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






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






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






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






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






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






48. A cell that can differentiate into many different cell types






49. Discovered mitosis






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