| Water vapor | Plants lose large amounts of this every day. |
| Stomata | The small openings in a leaf through which oxygen, carbon dioxide, and water pass. |
| Guard cells | These control the size of the openings (stomata) in a leaf. |
| Transpiration | The process by which a leaf loses water vapor. |
| Photosynthesis | The process in which a plant uses light to produce food. |
| Sunlight | During photosynthesis, a plant uses this to change water and carbon dioxdie into sugar and oxygen. |
| Chlorophyll | The green pigment in a plant that traps sunlight. |
| Blue, violet, and red light | The parts of the light spectrum that chlorophyll absorbs. |
| Green light | The part of the light spectum that chlorophyll reflects. |
| Carbon dioxide, water, and energy | The end products of respiration. |
| Sugar and oxygen | The end products of photosynthesis. |
| In respiration, is energy stored or released? | It's released! |
| In photosynthesis, is energy stored or released? | It's stored! |
| What two processes are linked? | Photosynthesis and respiration. |
