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






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






3. Useful for tearing and scratching






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






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






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






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






8. Organelle containing enzymes used in cell digestion






9. Any cell in a multicellular organism except the gametes






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






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






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






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






14. Brain and spinal cord






15. Epidermis - vascular - ground






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






17. Discovered mitosis






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






19. Plant with specialized tissue for conducting water and nutrients






20. Organelle in which proteins are synthesized






21. Connective - muscle - nervous - epithelial






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






23. Stores solid waste products






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






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






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






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






28. Produces digestive enzymes and the hormones insulin and glucagons






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






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






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






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






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






34. Stores and releases bile






35. 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






36. xylem and phloem; transport fluid and nutrients internally






37. Produce testosterone and sperm






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






39. Produce progesterone and estrogens - in addition to eggs






40. Cells that form the outer surface of plants






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






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






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






44. Organelle containing genetic material






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






46. 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






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






48. 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.






49. Sweat glands and sebaceous glands






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