|---|
| Cell membrane | Thin, flexible barrier around the cell; regulates what enters and leaves the cell |
| Cell wall | Provides support and protection for plant cells |
| Chlorophyll | The green pigment found in plants |
| Chloroplasts | Use the energy from sunlight to make energy-rich food molecules; found in plants |
| Cytoplasm | The area between the nucleus and the cell membrane |
| Golgi bodies | Attach carbohydrates and lipids to proteins |
| Lysosomes | Small organelles filled with enzymes; break down lipids, carbohydrates, and proteins from food |
| Microtubules | Hollow tubes of protein that maintain cell shape |
| Mitochondria | Use energy from food to make high-energy compounds that the cell can use to power growth, development, and movement |
| Nucleolus | A small, dense region in the nucleus that makes ribosomes |
| Nucleus | Controls most cell processes and contain the hereditary information of DNA |
| Ribosomes | Small particles made of RNA; assemble proteins |
| Rough endoplasmic reticulum | Involved in the synthesis of proteins; has ribosomes attached to its surface |
| Smooth endoplasmic reticulum | Contain collections of enzymes that perform tasks such as the synthesis of lipids; does not have ribosomes attached to its surface |
| Vacuole | Saclike structures that store water, salts, proteins, and carbohydrates |
