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. 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






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






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






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






5. Process that results in cell division






6. 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.






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






8. Holds tissues together






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






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






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






12. Brain and spinal cord






13. Produces and stores nutrients through photosynthesis






14. Any cell in a multicellular organism except the gametes






15. Organelle in which calcium levels are regulated






16. 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






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






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






19. 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






20. Stores and releases bile






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






22. xylem and phloem; transport fluid and nutrients internally






23. Protects the body and holds in heat






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






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






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






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






28. Attaches to bones and is responsible for voluntary movements






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






30. 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.






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






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






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






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






35. Produce testosterone and sperm






36. Stores solid waste products






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






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






39. Discovered mitosis






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






41. Organelle containing genetic material






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






43. Organelle containing enzymes used in cell digestion






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






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






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






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






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






49. Process that results in cell division to produce gametes






50. The basic structural and functional unit of all organisms
