| Organelle | Tiny cell structures that carry out specific functions |
| Cell Wall | A rigid layer of nonliving material in plant cells that surrounds the cell and helps to protect and support the cell. |
| Cell Membrane | Forms the outside boundary of a cell and controls what substances come into and out of the cell. |
| Nuclear Envelope | Surrounds the nucleus and protects it. Materials move into and out of the nucleus through its pores. |
| Lysosomes | Contain chemicals that break down certain materials in the cell. |
| Cytoplasm | A gel-like fluid containing dissolved substances and suspending many different organelles. |
| Nucleolus | Where ribosomes are made. |
| Mitochondria | Convert energy to in food molecules to energy the cell can use. |
| Endoplasmic rediculum | Passageways that carry proteins and other materials from one part of the cell to another. |
| Ribosome | Where proteins are produced. |
| Golgi Body | Receives proteins from the endoplasmic reticulum, packages them, and distributes them to other parts of the cell. |
| Chloroplasts | Capture energy from sunlight and use it to produce food for the cell. |
| Vacuoles | Storage areas of the cells, they store food or waste. |
| Chromatin | Genetic material containing instructions for directing the cell's functions. |
| Nucleus | The cell's control center, directing all of the cell's activities. |
