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






2. Discovered meiosis






3. Attaches to bones and is responsible for voluntary movements






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






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






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






7. Responsible for transporting materials throughout the body: heart - blood (red - white - platelets) - blood vessels (arteries - vein - capillaries)






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






9. 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.






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






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






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






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






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






15. Discovered mitosis






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






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






18. Produce testosterone and sperm






19. Plant with specialized tissue for conducting water and nutrients






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






21. Connective - muscle - nervous - epithelial






22. 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






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






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






25. Process that results in cell division to produce gametes






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






27. Release of water from plants through stomata






28. Produces digestive enzymes and the hormones insulin and glucagons






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






30. Cells that form the outer surface of plants






31. Brain and spinal cord






32. Produce progesterone and estrogens - in addition to eggs






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






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






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






36. xylem and phloem; transport fluid and nutrients internally






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






38. The basic structural and functional unit of all organisms






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






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






41. Organelle in which proteins are synthesized






42. 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






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






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






45. Organelle containing enzymes used in cell digestion






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






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






49. 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






50. Ability of a cell to differentiate into multiple different types of cells
