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. Organelle in which calcium levels are regulated






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






3. Organelle containing genetic material






4. Plant with specialized tissue for conducting water and nutrients






5. Organelle in which proteins are synthesized






6. 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






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






8. Useful for tearing and scratching






9. Organelle containing enzymes used in cell digestion






10. Produces digestive enzymes and the hormones insulin and glucagons






11. Stores and releases bile






12. Holds tissues together






13. Contracts or shortens making body parts move






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






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






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






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






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






19. The basic structural and functional unit of all organisms






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






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






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






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






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






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






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






27. Process that results in cell division






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






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






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






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






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






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






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






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






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






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






38. Discovered mitosis






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






40. 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.






41. Release of water from plants through stomata






42. 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.






43. Epidermis - vascular - ground






44. Protects the body and holds in heat






45. A doubled rod of condensed chromatin; contains DNA that carries genetic information.






46. Produce progesterone and estrogens - in addition to eggs






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






48. xylem and phloem; transport fluid and nutrients internally






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






50. Produces and stores nutrients through photosynthesis
