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






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






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






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






5. Process that results in cell division






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






7. Holds tissues together






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






9. xylem and phloem; transport fluid and nutrients internally






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






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






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






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






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






15. 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.






16. Division of the cytoplasm during cell division






17. Produce progesterone and estrogens - in addition to eggs






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






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






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






21. 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






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






23. Discovered meiosis






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






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






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






27. 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.






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






29. 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






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






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






32. Process that results in cell division to produce gametes






33. Epidermis - vascular - ground






34. Release of water from plants through stomata






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






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






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






38. Organelle in which calcium levels are regulated






39. Contracts or shortens making body parts move






40. Organelle containing enzymes used in cell digestion






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






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






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






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






45. 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.






46. Protects the body and holds in heat






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






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






49. Membrane - bound and fluid filled organelle in plant of fungal cells; also found in some bacterial - protist - and animal cells






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