2. controls all cell activities
7. found only in plant cells
8. a tough, rigid structure lying just outside a plant cells membrane, not found in animal cells
10. where energy is released from glucose to fuel cell activities
11. help to produce protein
12. filaments and tubules that provide a framework for the cell

1. contains water and other materials and are used to store or transport small molecules
3. membrane-covered sacs that transport and/or store materials inside the cell and sometimes help these materials to cross the cell membrane to enter or exit the cell
4. includes organelles, and other life supporting materials, such as sugar and water, all contained by the cell membrane
5. Separates the inside of the cell from the external environment
6. Involves directing sound waves at a body part and measuring reflected sound waves to make an image
9. Is conducted with a scope made up or a tiny camera and a light, which are attached to a flexible tube which is inserted into the body.
