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. Produce testosterone and sperm






2. 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






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






4. Protects the body and holds in heat






5. 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.






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






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






8. xylem and phloem; transport fluid and nutrients internally






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






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






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






12. Useful for tearing and scratching






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






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






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






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






17. Discovered meiosis






18. Organelle containing enzymes used in cell digestion






19. Stores and releases bile






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






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






22. Largest organ in terms of surface area






23. Release of water from plants through stomata






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






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






26. Division of the cytoplasm during cell division






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






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






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






30. Organelle in which proteins are synthesized






31. Sweat glands and sebaceous glands






32. Organelle containing genetic material






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






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






35. Stores solid waste products






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






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






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






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






40. Holds tissues together






41. The basic structural and functional unit of all organisms






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






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






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






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






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






48. Epidermis - vascular - ground






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






50. Brain and spinal cord
