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. Connective - muscle - nervous - epithelial






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






4. Organelle containing enzymes used in cell digestion






5. 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.






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






7. Discovered meiosis






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






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






10. 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






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






12. Stores and releases bile






13. A doubled rod of condensed chromatin; contains DNA that carries genetic information.






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






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






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






17. Largest organ in terms of surface area






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






19. Division of the cytoplasm during cell division






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






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






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






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






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






25. Useful for tearing and scratching






26. Brain and spinal cord






27. Holds tissues together






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






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






30. Process that results in cell division to produce gametes






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






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






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






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






35. Organelle containing genetic material






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






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






38. Eukaryotic organism that is not an animal - a plant - or a fungus.






39. Release of water from plants through stomata






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






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






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






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






44. Produce testosterone and sperm






45. 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.






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






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






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






49. 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






50. Any cell in a multicellular organism except the gametes
