Across
  1. 4. A jellylike fluid inside the cell in which the organelles are suspended
  2. 6. flexible double-layered sheet that makes up the cell membrane and forms a barrier between the cell and its surroundings
  3. 9. cell organelle filled with enzymes needed to break down certain materials in the cell
  4. 11. A network of fibers that holds the cell together, helps the cell to keep its shape, and aids in movement
  5. 12. A tiny cell structure that carries out a specific function within the cell
  6. 14. Hairlike projections that extend from the plasma membrane and are used for locomotion
  7. 15. A unicellular organism that lacks a nucleus and membrane bound organelles
  8. 16. The basic unit of structure and function in living things
  9. 18. A cell that contains a nucleus and membrane bound organelles
  10. 19. organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
  11. 20. Cytoplasmic organelles at which proteins are synthesized.
Down
  1. 1. A long, whip-like filament that helps in cell motility. Many bacteria are flagellated, and sperm are flagellated.
  2. 2. Cell organelle that stores materials such as water, salts, proteins, and carbohydrates
  3. 3. theory that eukaryotic cells formed from a symbiosis among several different prokaryotic organisms
  4. 4. thin, flexible barrier around a cell; regulates what enters and leaves the cell
  5. 5. idea that all living things are composed of cells, cells are the basic units of structure and function in living things, and new cells are produced from existing cells
  6. 7. stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum
  7. 8. A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
  8. 10. a property of cell membranes that allows some substances to pass through, while others cannot
  9. 11. A rigid layer of nonliving material that surrounds the cells of plants and some other organisms.
  10. 13. A part of the cell containing DNA and RNA and responsible for growth and reproduction
  11. 17. An organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur.
