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






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






3. xylem and phloem; transport fluid and nutrients internally






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






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






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






7. Stores and releases bile






8. 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.






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






10. Produces digestive enzymes and the hormones insulin and glucagons






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






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






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






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






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






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






17. Stores solid waste products






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






19. Discovered meiosis






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






21. Plant with specialized tissue for conducting water and nutrients






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






23. Connective - muscle - nervous - epithelial






24. Useful for tearing and scratching






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






26. Process that results in cell division






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






28. Any cell in a multicellular organism except the gametes






29. Produce progesterone and estrogens - in addition to eggs






30. 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






31. Contracts or shortens making body parts move






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






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






34. Process that results in cell division to produce gametes






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






36. Protects the body and holds in heat






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






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






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






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






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






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






43. 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.






44. Made up of celluolose - protein - and lignin - and allows pressure in plant cells to increase without the cell bursting.






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






46. Produce testosterone and sperm






47. The basic structural and functional unit of all organisms






48. Organelle in which calcium levels are regulated






49. Organelle containing genetic material






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