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. Process that results in cell division to produce gametes






2. Holds tissues together






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






4. Useful for tearing and scratching






5. 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






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






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






8. Organelle in eukaryotic cells that produces chemical energy; have their own DNA and may have evolved from a symbiotic relationship between a primitive eukaryotic organism and a primitive bacteria






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






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






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






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






13. Produce progesterone and estrogens - in addition to eggs






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






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






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






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






18. Discovered mitosis






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






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






21. The basic structural and functional unit of all organisms






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






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






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






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






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






27. Attaches to bones and is responsible for voluntary movements






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






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






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






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






32. Sweat glands and sebaceous glands






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






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






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






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






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






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






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






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






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






42. 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






43. Stores and releases bile






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






45. Connective - muscle - nervous - epithelial






46. 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.






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






48. 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






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






50. Stores solid waste products
