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






2. Produces and stores nutrients through photosynthesis






3. Plant with specialized tissue for conducting water and nutrients






4. 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






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






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






7. Protects the body and holds in heat






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






9. Attaches to bones and is responsible for voluntary movements






10. Epidermis - vascular - ground






11. Organelle containing enzymes used in cell digestion






12. 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






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






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






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






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






17. Cells that form the outer surface of plants






18. 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.






19. Brain and spinal cord






20. Responsible for the breakdown and absorption of food and the removal of solid waste; include the alimentary canal (mouth - esophagus - stomach - small intestine - large intestine - colon/ rectum) and the accessory organs (liver - pancreas - gall blad






21. Largest organ in terms of surface area






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






23. Connective - muscle - nervous - epithelial






24. 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.






25. 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






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






27. Process that results in cell division






28. Organelle in which calcium levels are regulated






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






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






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






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






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






34. Responsible for digesting and absorbing the extracted vital nutrients from food






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






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






37. Release of water from plants through stomata






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






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






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






41. Produce testosterone and sperm






42. Obsolete taxonomic group containing bacteria and cyanobacteria






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






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






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






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






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






48. xylem and phloem; transport fluid and nutrients internally






49. Dense portion of the nucleus; contains RNA and is involved in protein synthesis






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