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. xylem and phloem; transport fluid and nutrients internally






2. Plant with specialized tissue for conducting water and nutrients






3. 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.






4. 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






5. Process that results in cell division






6. Brain and spinal cord






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






8. Any cell in a multicellular organism except the gametes






9. 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






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






11. Organelle containing enzymes used in cell digestion






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






13. 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






14. Organelle in which proteins are synthesized






15. 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.






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






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






18. Region of condense chromosome that looks pinched; where spindle fibers attach during meiosis and mitosis.






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






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






21. Connective - muscle - nervous - epithelial






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






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






24. Release of water from plants through stomata






25. Largest organ in terms of surface area






26. 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.






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






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






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






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






31. 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






32. Produces and stores nutrients through photosynthesis






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






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






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






36. The basic structural and functional unit of all organisms






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






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






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






40. Contracts or shortens making body parts move






41. Discovered meiosis






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






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






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






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






46. Stores solid waste products






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






48. Cells that form the outer surface of plants






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






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