A | B |
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 |
