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. Useful for tearing and scratching






2. Discovered mitosis






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






4. 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






5. Attaches to bones and is responsible for voluntary movements






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






7. 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






8. Connective - muscle - nervous - epithelial






9. 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






10. Produce testosterone and sperm






11. 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.






12. Division of the cytoplasm during cell division






13. 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






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






15. 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.






16. Organelle containing genetic material






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






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






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






20. Protects the body and holds in heat






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






22. Organelle in which proteins are synthesized






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






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






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






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






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






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






29. Largest organ in terms of surface area






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






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






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






33. Produces and stores nutrients through photosynthesis






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






35. The basic structural and functional unit of all organisms






36. Release of water from plants through stomata






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






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






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






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






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






42. 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.






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






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






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






46. Responsible for the collection - transference - and the processing of external and internal information throughout the body; central nervous system - peripheral nervous system






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






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






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






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