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






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






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






4. 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






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






6. Organelle in which calcium levels are regulated






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






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






9. Process that results in cell division






10. Attaches to bones and is responsible for voluntary movements






11. Discovered mitosis






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






13. Your first line of defense against disease and helps regulate body temperature; skin - glands - hair - nails






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






15. 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.






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






17. Last stage of mitosis - in which the cell membrane begins to pinch the cell in two - cytokinesis begins - and the nuclear membrane forms around the chromosomes






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






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






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






21. Release of water from plants through stomata






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






23. Organelle containing enzymes used in cell digestion






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






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






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






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






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






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






30. Sweat glands and sebaceous glands






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






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






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






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






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






36. Discovered meiosis






37. Stores and releases bile






38. xylem and phloem; transport fluid and nutrients internally






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






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






41. Organelle in which proteins are synthesized






42. Organelles critical to protein synthesis found in the cytoplasm - joined to the endoplasmic reticulum - and within the mitochondria






43. The basic structural and functional unit of all organisms






44. Epidermis - vascular - ground






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






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






47. 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.






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






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






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