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






2. Largest organ in terms of surface area






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






4. Stores solid waste products






5. xylem and phloem; transport fluid and nutrients internally






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






7. 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.






8. 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.






9. Organelle in which calcium levels are regulated






10. Produces and stores nutrients through photosynthesis






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






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






13. Process that results in cell division to produce gametes






14. Release of water from plants through stomata






15. Organelle containing enzymes used in cell digestion






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






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






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






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






20. Sweat glands and sebaceous glands






21. Obsolete taxonomic group containing bacteria and cyanobacteria






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






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






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






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. Contracts or shortens making body parts move






27. Responsible for defending the body against disease - causing agents; white blood cells (macrophages - B- cells and T- cells) - lymph nodes






28. Attaches to bones and is responsible for voluntary movements






29. Discovered mitosis






30. 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






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






32. Holds tissues together






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






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






35. Connective - muscle - nervous - epithelial






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






37. Cells that form the outer surface of plants






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






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






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






41. Brain and spinal cord






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






43. Plant with specialized tissue for conducting water and nutrients






44. Produces digestive enzymes and the hormones insulin and glucagons






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






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






47. Thin layer of plant tissue just below the bark which produces the xylem






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






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






50. Division of the cytoplasm during cell division
