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






2. Largest organ in terms of surface area






3. Located close to the kidneys. Responsible for releasing adrenaline - a hormone that produces the flight or fight response.






4. Produce testosterone and sperm






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






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






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






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






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






10. Epidermis - vascular - ground






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






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






13. Obsolete taxonomic group containing bacteria and cyanobacteria






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






15. Useful for tearing and scratching






16. Responsible for providing voluntary and involuntary movement; cardiac - skeletal - smooth






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






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






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






20. Produce progesterone and estrogens - in addition to eggs






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






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






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






24. Protects the body and holds in heat






25. Attaches to bones and is responsible for voluntary movements






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






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






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






29. Organelle in which proteins are synthesized






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






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






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






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






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






35. Discovered mitosis






36. Cells that form the outer surface of plants






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






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






39. 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.






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






41. Organelle in which calcium levels are regulated






42. An extensive membrane network of cisternae (sac - like structures) held together by the cytoskeleton that encloses the cisternal space (or lumen) from the cytosol and is continuous with the perinuclear space. Three types: RER - SER - SR






43. Division of the cytoplasm during cell division






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






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






46. Produces digestive enzymes and the hormones insulin and glucagons






47. Organelle containing enzymes used in cell digestion






48. Process that results in cell division






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






50. 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.
