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. Organelle containing enzymes used in cell digestion






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






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






5. Produces digestive enzymes and the hormones insulin and glucagons






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






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






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






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






10. Discovered meiosis






11. Organelle in which calcium levels are regulated






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






13. Sweat glands and sebaceous glands






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






15. Division of the cytoplasm during cell division






16. The basic structural and functional unit of all organisms






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






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






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






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






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






22. Cells that form the outer surface of plants






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






24. Brain and spinal cord






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






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






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






28. Organelle in which proteins are synthesized






29. 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






30. Produce testosterone and sperm






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






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






33. Process that results in cell division






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






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






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






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






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






39. Stores solid waste products






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






41. Contracts or shortens making body parts move






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






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






44. Discovered mitosis






45. Release of water from plants through stomata






46. xylem and phloem; transport fluid and nutrients internally






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






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






50. So named because it lacks striations. Involuntary muscle found along the walls of the digestive tract - bladder - arteries - and other internal organs.
