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






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






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






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






5. Discovered meiosis






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






7. Sweat glands and sebaceous glands






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






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






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






11. Stores solid waste products






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






13. Release of water from plants through stomata






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






15. Produces and stores nutrients through photosynthesis






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






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






18. 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.






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






20. Obsolete taxonomic group containing bacteria and cyanobacteria






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






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






23. Epidermis - vascular - ground






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






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






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 basic structural and functional unit of all organisms






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






29. Produces digestive enzymes and the hormones insulin and glucagons






30. Attaches to bones and is responsible for voluntary movements






31. Plant with specialized tissue for conducting water and nutrients






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






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






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






35. Organelle in which proteins are synthesized






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






37. Division of the cytoplasm during cell division






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






39. Useful for tearing and scratching






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






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






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






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






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






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






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






47. Produce progesterone and estrogens - in addition to eggs






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






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






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