Terms | Definitions |
|---|---|
 photosynthesis | the process by which plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high-energy carbohydrates such as sugars and starches. |
| cellular respiration | the process by which cells use oxygen gas to break down carbohydrates, releasing chemical energy that the cell can use |
| autotroph | organism that can capture energy from sunlight or chemicals and use it to produce its own food from inorganic compounds; also called a producer |
| heterotroph | organism that obtains energy from the foods it consumes; also called a consumer |
| glucose | the form of sugar that circulates in the blood and provides the major source of energy for body tissues |
| C6H12O6 | the chemical formula for glucose |
| stomata | the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move |
| chloroplast | organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy |
| chlorophyll | green pigment in plants that absorbs light energy used to carry out photosynthesis |
| mitochondria | the cells powerhouse, turning food into energy; the organelle where cellular respiration takes place. |
| pigment | a colored chemical compound that absorbs light |
| fermentation | the process by which cells break down carbohydrates to release energy without using oxygen |
| lactic acid | waste product produced by fermentation; causes muscles to be sore |
