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






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






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






4. Brain and spinal cord






5. Stores and releases bile






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






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






8. Organelle containing enzymes used in cell digestion






9. Division of the cytoplasm during cell division






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






11. Release of water from plants through stomata






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






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






14. Protects the body and holds in heat






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






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






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






18. Discovered meiosis






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






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






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






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






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






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






28. Obsolete taxonomic group containing bacteria and cyanobacteria






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






30. Useful for tearing and scratching






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






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






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






34. 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






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






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






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






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






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






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






41. Discovered mitosis






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






43. Connective - muscle - nervous - epithelial






44. The basic structural and functional unit of all organisms






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






46. Organism that harnesses light energy to produce organic materials from carbon dioxide and water






47. Produces hormones directly into the blood; pituitary gland - thyroid gland - adrenal glands - pancreas - ovaries - testes - thymus gland






48. Produces digestive enzymes and the hormones insulin and glucagons






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






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