Across
  1. 4. Controls which substances pass into and out of a cell
  2. 8. 1st to observe cells. Coined the term "cell".
  3. 9. Concluded that all plants are made of cells
  4. 11. 1st to observe living cells. Called them "animalcules"
  5. 13. The degree to which two separate structures that are close together can be distinguished (how clear the picture is)
  6. 14. Sac that stores water, food, or other materials needed by the cell
  7. 15. The condition of things appearing larger than they are
  8. 16. Proposed that "all cells come from existing cells"
  9. 17. Saclike organelles, which contain substances (enzymes) that break down large food particles into smaller ones (also old cell parts)
  10. 18. Green structures that capture energy from sunlight and change it to a form of energy cells can use in making food
  11. 20. Bread, pasta, rice, and other sugar/starches
  12. 22. “Powerhouse of the Cell,” convert energy stored in food to energy the cell can use to live and function
Down
  1. 1. Small grain-shaped organelles that produce proteins
  2. 2. Large oval structure that acts a s cell’s control center, directing all of the cell’s activities
  3. 3. Fats, waxes, and oils
  4. 5. ER, an organelle with a network of membranes that produces many substances (make protein with attached Ribosomes)
  5. 6. “Cell Warehouse,” packages proteins from the ER and distributes them to other parts of the cell or to the outside of the cell
  6. 7. A rigid layer that surround the cells of plants and some other organisms.
  7. 10. Thick, clear, gel-like fluid that fills the region between the cell membrane and the nucleus
  8. 12. Meat, Eggs, and other foods good for building muscles
  9. 19. Tiny cell structures that carry out specific functions within a cell
  10. 21. Concluded that all animals are made of cells
