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






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






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






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






6. 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






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






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






9. Contracts or shortens making body parts move






10. Process that results in cell division to produce gametes






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






12. Organelle in which calcium levels are regulated






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






14. Discovered mitosis






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






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






17. Process that results in cell division






18. Plant with specialized tissue for conducting water and nutrients






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






20. 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.






21. 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.






22. Stores and releases bile






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






24. Release of water from plants through stomata






25. Organelle containing genetic material






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






27. Discovered meiosis






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






29. 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






30. The basic structural and functional unit of all organisms






31. Organelle containing enzymes used in cell digestion






32. 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.






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






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






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






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






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






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






39. Stores solid waste products






40. Any cell in a multicellular organism except the gametes






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






42. Produces and stores nutrients through photosynthesis






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






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






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






46. Attaches to bones and is responsible for voluntary movements






47. 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






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






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






50. Brain and spinal cord
