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. Organelle in which calcium levels are regulated






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






3. Produce testosterone and sperm






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






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






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






7. Sweat glands and sebaceous glands






8. Organelle in which proteins are synthesized






9. Produce progesterone and estrogens - in addition to eggs






10. xylem and phloem; transport fluid and nutrients internally






11. Stores solid waste products






12. Process that results in cell division






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






14. 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






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






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






17. Largest organ in terms of surface area






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






19. Holds tissues together






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






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






22. Discovered meiosis






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






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






25. Brain and spinal cord






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






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






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






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






30. Produces hormones directly into the blood; pituitary gland - thyroid gland - adrenal glands - pancreas - ovaries - testes - thymus gland






31. Plant with specialized tissue for conducting water and nutrients






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






33. Produces and stores nutrients through photosynthesis






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






35. 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






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






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






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






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






40. Attaches to bones and is responsible for voluntary movements






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






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






43. Discovered mitosis






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






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






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






47. 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.






48. Useful for tearing and scratching






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






50. Obsolete taxonomic group containing bacteria and cyanobacteria
