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. Produce progesterone and estrogens - in addition to eggs






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






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






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






5. Largest organ in terms of surface area






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






7. Any cell in a multicellular organism except the gametes






8. Covers organ surfaces (skin - airways - reproductive tract - inner lining of the digestive tract)






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






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






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






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






13. Tiny nodules found all over the body. They contain a colorless fluid called lymph.






14. Cells that form the outer surface of plants






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






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






17. Division of the cytoplasm during cell division






18. Organelle containing enzymes used in cell digestion






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






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






21. Plant with specialized tissue for conducting water and nutrients






22. Contracts or shortens making body parts move






23. Attaches to bones and is responsible for voluntary movements






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






25. 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.






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






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






28. Produces and stores nutrients through photosynthesis






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






30. 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.






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






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






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






34. 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






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






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






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






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






39. Brain and spinal cord






40. Process that results in cell division to produce gametes






41. Epidermis - vascular - ground






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






43. 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






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






45. Discovered meiosis






46. Process that results in cell division






47. Organelle in which proteins are synthesized






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






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






50. 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
