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 containing genetic material






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






3. Produces and stores nutrients through photosynthesis






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






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






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






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






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






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






11. Produces digestive enzymes and the hormones insulin and glucagons






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






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






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






15. Stores and releases bile






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






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






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






19. Release of water from plants through stomata






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






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






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






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






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






25. Discovered mitosis






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






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






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






29. Useful for tearing and scratching






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






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






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






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






34. 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






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






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






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






38. Process that results in cell division






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






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






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






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






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






44. Largest organ in terms of surface area






45. Organelle in which proteins are synthesized






46. Produce progesterone and estrogens - in addition to eggs






47. 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.






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






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






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