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 lack membranous - structurally discrete organelles






2. Release of water from plants through stomata






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






4. Connective - muscle - nervous - epithelial






5. Process that results in cell division to produce gametes






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






7. xylem and phloem; transport fluid and nutrients internally






8. 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






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






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






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






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






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






14. Pores underneath plant leaves used to exchange carbon dioxide and oxygen






15. Stores solid waste products






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






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






18. Cells that form the outer surface of plants






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






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






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






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






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






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






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






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






27. Division of the cytoplasm during cell division






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






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






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






31. Produce testosterone and sperm






32. Largest organ in terms of surface area






33. 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.






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






35. Discovered meiosis






36. Protects the body and holds in heat






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






38. Obsolete taxonomic group containing bacteria and cyanobacteria






39. Useful for tearing and scratching






40. Plant with specialized tissue for conducting water and nutrients






41. Organelle containing enzymes used in cell digestion






42. 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.






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






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






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






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






47. Sweat glands and sebaceous glands






48. The basic structural and functional unit of all organisms






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






50. Organelle in which calcium levels are regulated
