Across
- 7. the transportation system of the eukaryotic cell, and has many other important functions such as protein folding
- 8. a microscopic network of protein filaments and tubules in the cytoplasm of many living cells, giving them shape and coherence.
- 9. mall, membrane-enclosed organelles that contain enzymes involved in a variety of metabolic reactions, including several aspects of energy metabolism.
- 12. is a cylindrical organelle composed mainly of a protein called tubulin.
- 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.
- 15. a molecule, consisting of hundreds – and sometimes even thousands – of carbon, hydrogen and oxygen atoms.
- 16. is any eukaryotic organism that is not an animal, plant, or fungus.
- 17. is a small, extrachromosomal DNA molecule within a cell
- 18. is the largest structure in the nucleus of eukaryotic cells.
Down
- 1. a subcellular structure that has one or more specific jobs to perform in the cell
- 2. a whip-like appendage on the cell body of certain cells. It is primarily involved in locomotion
- 3. (a prokaryotic cell) that contains the genetic material DNA and therefore controls the activity of the cell.
- 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. cell) a membrane-bound organelle that contains the cell's chromosomes.
- 6. Generates energy ATP
- 8. that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth.
- 10. short, hair-like structures on the cell surface of prokaryotic cells
- 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.
- 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.
- 15. a small case or container, especially a round or cylindrical one.
