  1. 7. the transportation system of the eukaryotic cell, and has many other important functions such as protein folding
  2. 8. a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.
  3. 9. mall, membrane-enclosed organelles that contain enzymes involved in a variety of metabolic reactions, including several aspects of energy metabolism.
  4. 12. is a cylindrical organelle composed mainly of a protein called tubulin.
  5. 14. hairlike vibrating structure found in large numbers on the surface of certain cells, either causing currents in the surrounding fluid, or, in some protozoans and other small organisms, providing propulsion.
  6. 15. a molecule, consisting of hundreds – and sometimes even thousands – of carbon, hydrogen and oxygen atoms.
  7. 16. is any eukaryotic organism that is not an animal, plant, or fungus.
  8. 17. is a small, extrachromosomal DNA molecule within a cell
  9. 18. is the largest structure in the nucleus of eukaryotic cells.

  1. 1. a subcellular structure that has one or more specific jobs to perform in the cell
  2. 2. a whip-like appendage on the cell body of certain cells. It is primarily involved in locomotion
  3. 3. (a prokaryotic cell) that contains the genetic material DNA and therefore controls the activity of the cell.
  4. 4. the material of which the chromosomes of organisms other than bacteria (i.e., eukaryotes) are composed. It consists of protein, RNA, and DNA.
  5. 5. cell) a membrane-bound organelle that contains the cell's chromosomes.
  6. 6. Generates energy ATP
  7. 8. that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth.
  8. 10. short, hair-like structures on the cell surface of prokaryotic cells
  9. 11. a member of a large group of unicellular microorganisms which have cell walls but lack organelles and an organized nucleus, including some that can cause disease.
  10. 13. a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria. In the algae and higher plants it consists mainly of cellulose.
  11. 15. a small case or container, especially a round or cylindrical one.
