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






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






3. Organelle containing enzymes used in cell digestion






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






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






6. Stores solid waste products






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






8. Discovered meiosis






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






10. Useful for tearing and scratching






11. Release of water from plants through stomata






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






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






14. Process that results in cell division to produce gametes






15. Cells that form the outer surface of plants






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






17. Sweat glands and sebaceous glands






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






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






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






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






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






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






24. Plant with specialized tissue for conducting water and nutrients






25. 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






26. Produce progesterone and estrogens - in addition to eggs






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






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






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






30. Protects the body and holds in heat






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






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






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






34. Holds tissues together






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






36. Epidermis - vascular - ground






37. Chlorophyll containing plant cell organelle within which photosynthesis takes place






38. Responsible for the breakdown and absorption of food and the removal of solid waste; include the alimentary canal (mouth - esophagus - stomach - small intestine - large intestine - colon/ rectum) and the accessory organs (liver - pancreas - gall blad






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






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






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






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






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






44. Organelle in which calcium levels are regulated






45. 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.






46. 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.






47. 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






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






49. Any cell in a multicellular organism except the gametes






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