|---|
| force | capacity to do work |
| photosynthesis | process of making food using sunlight |
| chloroplast | part of cell where photosynthesis takes place |
| Ingredients for photosynthesis | sunlight, carbon dioxide, water |
| sugar | water and carbon dioxide combine inside the chloroplast to make this |
| friction | a force that resists the relative motion of two substances in contact |
| xylem | plant tissue in which the roots suck the water |
| stomata | where the carbon dioxide enters the leaf |
| the role of plants | plants take in CO2 and give off O2 |
| guard cells | open and close to allow gases to enter and exit |
| stomata function | closes when drought and opens when wet |
| waxy cuticle | keeps water from escaping |
| starch | the sugar produced by photosynthesis is stored as this |
| phloem | transports the sugar |
| carbohydrate | group of chem compounds made of carbon, hydrogen, oxygen |
| cellular respiration | the opposite of photosynthesis |
| 10% | amount of energy that gets turned into food energy |
| energy pyramid | diagrams amount of energy at each level of an ecosystem |
| 90% | is not turned into food energy |
