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






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






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






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






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






6. Connective - muscle - nervous - epithelial






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






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






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






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






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






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






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






14. Produce progesterone and estrogens - in addition to eggs






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






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






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






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






19. Organisms with cells that lack membranous - structurally discrete organelles






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






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






22. Organelle containing genetic material






23. Cells that form the outer surface of plants






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






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






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






27. Stores solid waste products






28. Useful for tearing and scratching






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






30. Organelle containing enzymes used in cell digestion






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






32. Largest organ in terms of surface area






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






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






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






36. Contracts or shortens making body parts move






37. Any cell in a multicellular organism except the gametes






38. Produces and stores nutrients through photosynthesis






39. Plant with specialized tissue for conducting water and nutrients






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






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






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






43. Protects the body and holds in heat






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






45. Process that results in cell division






46. Process that results in cell division to produce gametes






47. Stores and releases bile






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






49. xylem and phloem; transport fluid and nutrients internally






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