5. the basic unit of structure and function in all organisms
7. thin, flexible outer layer that holds the cell together and controls which materials enter and leave the cell
8. store water, salt, protein and carbohydrates in the cell
12. the process by which cells break down sugar to release stored energy
13. organelles that release energy from glucose
15. a structure inside a cell that carries out a certain function
17. organisms whose cells lack a distinct nucleus and organelles
19. broken down quickly to release energy

1. large structure inside the cell that controls many functions of the cell
2. the process in which the cells of plants and some other organisms use the energy of sunlight to make food
3. a protective layer that surrounds the cell membrane of plant cells
4. organisms whose cells have a distinct nucleus and organelles
5. a structure in the nucleus of a cell that contains the cell's genetic material
6. the compounds that provide energy and building materials for living things
9. organelles that make food for a plant cell
