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






2. Process that results in cell division






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






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






5. Release of water from plants through stomata






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






7. Produces digestive enzymes and the hormones insulin and glucagons






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






9. Attaches to bones and is responsible for voluntary movements






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






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






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






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






14. Organelle containing enzymes used in cell digestion






15. Process that results in cell division to produce gametes






16. The basic structural and functional unit of all organisms






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






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






19. Protects the body and holds in heat






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






21. Any cell in a multicellular organism except the gametes






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






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






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






25. Largest organ in terms of surface area






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






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






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






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






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






31. Stores and releases bile






32. Discovered meiosis






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






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






35. 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






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






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






38. xylem and phloem; transport fluid and nutrients internally






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






40. Sweat glands and sebaceous glands






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






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






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






45. Connective - muscle - nervous - epithelial






46. Brain and spinal cord






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






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






49. 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






50. 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.
