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. A cell that can differentiate into many different cell types






2. Discovered mitosis






3. Process that results in cell division to produce gametes






4. Brain and spinal cord






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






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






7. Produces digestive enzymes and the hormones insulin and glucagons






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






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






10. Useful for tearing and scratching






11. 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






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






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






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






15. Produce progesterone and estrogens - in addition to eggs






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






17. 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






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






19. 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.






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






21. Discovered meiosis






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






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






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






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






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






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






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






29. 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.






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






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






32. Epidermis - vascular - ground






33. 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






34. Contracts or shortens making body parts move






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






37. Circulates through the vessels of the lymphatic system - which in turn assists the immune system.






38. The basic structural and functional unit of all organisms






39. Plant with specialized tissue for conducting water and nutrients






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






41. Holds tissues together






42. Process that results in cell division






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






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






45. Largest organ in terms of surface area






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






47. Protects the body and holds in heat






48. Organelle in which calcium levels are regulated






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






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