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. Chlorophyll containing plant cell organelle within which photosynthesis takes place






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






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






4. Any cell in a multicellular organism except the gametes






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






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






7. Epidermis - vascular - ground






8. Cells that form the outer surface of plants






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






10. Discovered mitosis






11. 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.






12. Process that results in cell division to produce gametes






13. Contracts or shortens making body parts move






14. Connective - muscle - nervous - epithelial






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






16. 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.






17. xylem and phloem; transport fluid and nutrients internally






18. Produce testosterone and sperm






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






20. Attaches to bones and is responsible for voluntary movements






21. Stores solid waste products






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






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






24. 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.






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






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






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






28. Organelle in which calcium levels are regulated






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






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






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






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






33. Produces and stores nutrients through photosynthesis






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






35. Useful for tearing and scratching






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






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






38. Discovered meiosis






39. Produces digestive enzymes and the hormones insulin and glucagons






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






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






42. 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






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






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






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






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






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






48. Organelle in which proteins are synthesized






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






50. Obsolete taxonomic group containing bacteria and cyanobacteria
