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. Produce testosterone and sperm






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






3. Produces digestive enzymes and the hormones insulin and glucagons






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






5. Connective - muscle - nervous - epithelial






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






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






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






9. Protects the body and holds in heat






10. Produce progesterone and estrogens - in addition to eggs






11. Organelle in which proteins are synthesized






12. Connections between plant cells that allow fluids and nutrients to be shared






13. 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






14. Process that results in cell division






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






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






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






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






19. Discovered mitosis






20. Any cell in a multicellular organism except the gametes






21. 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.






22. Largest organ in terms of surface area






23. Cells that form the outer surface of plants






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






25. xylem and phloem; transport fluid and nutrients internally






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






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






28. Division of the cytoplasm during cell division






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






30. Plant with specialized tissue for conducting water and nutrients






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






32. Organelle containing enzymes used in cell digestion






33. Process that results in cell division to produce gametes






34. Brain and spinal cord






35. 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.






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






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






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






39. Contracts or shortens making body parts move






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






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






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






43. The basic structural and functional unit of all organisms






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






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






46. Obsolete taxonomic group containing bacteria and cyanobacteria






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






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






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






50. 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
