| A | B |
| endoplasmic reticulum | network of passageways carries materials from one part of cell to another |
| vacuole | storage for water, food waste products and other materials |
| cell wall | stiff wall that surrounds the cell membrane; found only in plant cells |
| cell membrane | regulates what enters and leaves the cell |
| chloroplast | capture energy from sunlight and use it to produce food for the cell |
| nucleus | control center of the cell |
| cytoplasm | the area between cell membrane and nucleus; many organelles are found here |
| mitochondria | respiration to produce energy occurs here |
| ribosomes | proteins are produced here |
| cellular respiration | glucose + oxygen produces energy carbon dioxide and water |
| photosynthesis | carbon dioxide + water and sunlight produces oxygen and glucose |
