Photosynthesis & CR
| Question | Answer |
|---|---|
| Autotroph | An organism that makes its own food using energy from the sun or chemicals. Plants are autotrophs. |
| Chlorophyll | The green pigment in plant cells that captures light energy from the sun. It gives plants their green color. |
| Chloroplast | The organelle in plant cells where photosynthesis happens. It contains chlorophyll and is where plants make their own food. |
| Cytoplasm | The jelly-like substance inside a cell that fills the space between the cell membrane and the nucleus. Organelles float in it. |
| Heterotroph | An organism that cannot make its own food and must eat other organisms to survive. Animals are heterotrophs. |
| Mitochondria | The organelle in cells that breaks down food to release energy. It is the "powerhouse" of the cell. |
| Photosynthesis | The process plants use to make their own food using sunlight, water, and carbon dioxide. It happens in the chloroplasts. |
| Products | The substances made at the end of a chemical reaction. In photosynthesis, the products are glucose and oxygen. |
| Raw Materials/Reactants | The substances you start with at the beginning of a chemical reaction. In photosynthesis, the raw materials are sunlight, water, and carbon dioxide. |
| Cellular Respiration | The process cells use to break down glucose and release energy. It happens in the mitochondria and provides energy for the cell to use. |
| Stomata | Tiny pores on the underside of plant leaves that open and close. They allow carbon dioxide to enter the plant and oxygen to exit. |
