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






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






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






4. Produces and stores nutrients through photosynthesis






5. Organelle containing enzymes used in cell digestion






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






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






8. Plant with specialized tissue for conducting water and nutrients






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






10. 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






11. Cells that form the outer surface of plants






12. Holds tissues together






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






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






15. Stores solid waste products






16. 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.






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






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






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






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






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






22. Useful for tearing and scratching






23. Protects the body and holds in heat






24. Process that results in cell division to produce gametes






25. Organelle containing genetic material






26. Sweat glands and sebaceous glands






27. Process that results in cell division






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






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






30. Largest organ in terms of surface area






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






32. Any cell in a multicellular organism except the gametes






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






34. Small sac within a cell formed by pinching of some membrane; can contain waste - products the cell is taking in - and secretions the cell is exporting






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






36. 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






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






38. Division of the cytoplasm during cell division






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






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






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






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






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






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






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






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






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






48. Stores and releases bile






49. Contracts or shortens making body parts move






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