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. Produces and stores nutrients through photosynthesis






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






3. 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.






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






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






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






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






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






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






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






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






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






13. Discovered mitosis






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






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






16. The basic structural and functional unit of all organisms






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






18. Epidermis - vascular - ground






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






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






21. Covers organ surfaces (skin - airways - reproductive tract - inner lining of the digestive tract)






22. Obsolete taxonomic group containing bacteria and cyanobacteria






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






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






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






26. Any cell in a multicellular organism except the gametes






27. Organisms with cells that lack membranous - structurally discrete organelles






28. Holds tissues together






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






30. Process that results in cell division to produce gametes






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






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






33. Produce testosterone and sperm






34. Stores solid waste products






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






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






37. 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






38. 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.






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






40. Organelle in which calcium levels are regulated






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






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






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






44. 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






45. Cells that form the outer surface of plants






46. 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






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






48. Sweat glands and sebaceous glands






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






50. Attaches to bones and is responsible for voluntary movements
