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






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






3. Produce testosterone and sperm






4. Discovered mitosis






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






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






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






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






9. Stores solid waste products






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






11. 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.






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






13. Sweat glands and sebaceous glands






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






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






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






17. 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






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






19. Produce progesterone and estrogens - in addition to eggs






20. Produces digestive enzymes and the hormones insulin and glucagons






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






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






23. Stores and releases bile






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






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






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






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






28. 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






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






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






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






32. Holds tissues together






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






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






35. 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.






36. Connective - muscle - nervous - epithelial






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






38. Useful for tearing and scratching






39. The basic structural and functional unit of all organisms






40. Protects the body and holds in heat






41. Organelle in which proteins are synthesized






42. Organelle in which calcium levels are regulated






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






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






45. Organelle containing enzymes used in cell digestion






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






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






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






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






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