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






2. Stores solid waste products






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






4. The basic structural and functional unit of all organisms






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






6. Brain and spinal cord






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






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






9. Holds tissues together






10. Connective - muscle - nervous - epithelial






11. Stores and releases bile






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






13. 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.






14. So named because it lacks striations. Involuntary muscle found along the walls of the digestive tract - bladder - arteries - and other internal organs.






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






16. Responsible for digesting and absorbing the extracted vital nutrients from food






17. 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






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






19. A haploid reproductive cell that unites with another haploid reproductive cell to form a zygote






20. Discovered meiosis






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






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






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






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






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






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






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






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






29. Useful for tearing and scratching






30. 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.






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






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






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






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






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






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






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






38. Involuntary muscle that forms the contractile walls of the heart






39. Process that results in cell division to produce gametes






40. Obsolete taxonomic group containing bacteria and cyanobacteria






41. Produces digestive enzymes and the hormones insulin and glucagons






42. 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






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






44. Circulates through the vessels of the lymphatic system - which in turn assists the immune system.






45. 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






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






47. xylem and phloem; transport fluid and nutrients internally






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






49. Organelle in which proteins are synthesized






50. Sweat glands and sebaceous glands
