Across
  1. 2. network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement.
  2. 5. basic unit of all forms of life.
  3. 6. converts the chemical energy stored in food into compounds that are more convenient for the cell to use.
  4. 9. gives cell membranes a flexible double layer structure that forms a strong barrier between the cell and its surroundings.
  5. 12. internal membrane system found in eukaryotic cells; place where lipid components of the cell membrane are assembled.
  6. 14. structure to help organize cell division. NOT found in plant cells only animal cells.
  7. 15. it captures the energy from sunlight and convert it into food that contains chemical energy in a process called photosynthesis.
  8. 16. are large saclike membrane-enclosed structures. It stores materials such as water, salts, proteins, and carbohydrates.
