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 lipids and steroids are produced - carbohydrates and steroids are metabolized - and calcium concentration - drug detoxification - and attachment of cell membrane receptors are regulated.






2. Organelle containing enzymes used in cell digestion






3. Process that results in cell division to produce gametes






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






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






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






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






8. Produces digestive enzymes and the hormones insulin and glucagons






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






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






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






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






13. Produce testosterone and sperm






14. Organelle in eukaryotic cells that produces chemical energy; have their own DNA and may have evolved from a symbiotic relationship between a primitive eukaryotic organism and a primitive bacteria






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






16. The basic structural and functional unit of all organisms






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






18. 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.






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






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






21. 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






22. Epidermis - vascular - ground






23. 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






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






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






26. Brain and spinal cord






27. 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






28. Obsolete taxonomic group containing bacteria and cyanobacteria






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






30. Attaches to bones and is responsible for voluntary movements






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






32. Process that results in cell division






33. Cells that form the outer surface of plants






34. Useful for tearing and scratching






35. Produce progesterone and estrogens - in addition to eggs






36. Connective - muscle - nervous - epithelial






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






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






39. Organelle in which proteins are synthesized






40. Plant with specialized tissue for conducting water and nutrients






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






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






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






44. Responsible for storing food and initiating the digestion of proteins






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






46. Protects the body and holds in heat






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






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






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






50. Discovered meiosis
