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. Division of the cytoplasm during cell division






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






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






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






5. 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






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






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






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






9. Organelle in which proteins are synthesized






10. 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






11. Plant with specialized tissue for conducting water and nutrients






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






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






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






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






16. 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.






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






18. Obsolete taxonomic group containing bacteria and cyanobacteria






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






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






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






23. Any cell in a multicellular organism except the gametes






24. Produces and stores nutrients through photosynthesis






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






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






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






28. 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.






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






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






31. Stores and releases bile






32. Discovered meiosis






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






34. Produce testosterone and sperm






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






36. Release of water from plants through stomata






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






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






39. Organelle containing enzymes used in cell digestion






40. Process that results in cell division to produce gametes






41. Organelle in which calcium levels are regulated






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






43. Contracts or shortens making body parts move






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






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






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






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






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






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