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. Stores solid waste products






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






3. 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.






4. Discovered mitosis






5. Largest organ in terms of surface area






6. Holds tissues together






7. Stores and releases bile






8. Attaches to bones and is responsible for voluntary movements






9. Contracts or shortens making body parts move






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






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






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






13. Any cell in a multicellular organism except the gametes






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






15. Sweat glands and sebaceous glands






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






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






18. 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






19. Division of the cytoplasm during cell division






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






21. Organelle containing genetic material






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






23. 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






24. Useful for tearing and scratching






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






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






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






28. Located in the neck area. Releases thyroxin - which regulates the body's metabolic rate.






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






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






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






32. 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.






33. 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






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






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






36. Epidermis - vascular - ground






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






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






39. 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.






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






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






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






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






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






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






46. Organelle in which calcium levels are regulated






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






48. xylem and phloem; transport fluid and nutrients internally






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






50. Produce progesterone and estrogens - in addition to eggs
