- 11. A rigid layer that surround the cells of plants and some other organisms
- 12. Sac that stores water, food, or other materials needed by the cell

- 1. First person to observe cells. Coined the term "Cell"
- 2. Tiny cell structures that carry out specific functions within a cell
- 3. Concluded that all plants are made of cells
- 4. “Cell Warehouse,” packages proteins from the ER and distributes them to other parts of the cell or to the outside of the cell
- 7. organelle with a network of membranes that produces many substances (make protein with attached Ribosomes)
- 9. 3 part idea that states that all living things are made of cells, cells are the basic unit of structure and function, and cells come from other cells
