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






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






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






4. Largest organ in terms of surface area






5. The basic structural and functional unit of all organisms






6. Stores solid waste products






7. Process that results in cell division






8. Discovered meiosis






9. Plant with specialized tissue for conducting water and nutrients






10. Release of water from plants through stomata






11. Cells that form the outer surface of plants






12. Any cell in a multicellular organism except the gametes






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






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






15. Division of the cytoplasm during cell division






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






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






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






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






20. Contracts or shortens making body parts move






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






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






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






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






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






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






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






28. Produces digestive enzymes and the hormones insulin and glucagons






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






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






31. Organelle in which calcium levels are regulated






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






33. Protects the body and holds in heat






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






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






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






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






38. Epidermis - vascular - ground






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






40. 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






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






42. 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.






43. Attaches to bones and is responsible for voluntary movements






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






45. Organelle that 'packages' proteins to be secreted from the cell






46. xylem and phloem; transport fluid and nutrients internally






47. 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






48. Produce progesterone and estrogens - in addition to eggs






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






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