Across
- 2. An organism that can make its own food. (plants, algae, and some bacteria)
- 3. energy energy from the sun that is converted to chemical energy during photosynthesis
- 4. dioxide gas breathed out by humans that is a reactant of photosynthesis
- 7. gas breathed in by humans that is a product of photosynthesis
- 8. the process plants use to convert light energy to chemical energy stored in a glucose (sugar) molecule
- 9. tiny holes on the bottom of the leaves of plants where gases like carbon dioxide and oxygen enter and exit
- 10. a type of simple sugar made during photosynthesis; stores energy and is used by plants and animals as "food"
Down
- 1. organelle found in plants, algae, and some bacteria where photosynthesis takes place
- 2. chemical compound that absorbs light and gives organisms their color
- 3. broad, flat structures in plants that absorb sunlight and are the site of photosynthesis
- 5. An organism that obtains energy by feeding on other organisms.
- 6. green pigment in the chloroplasts of plants, algae, and some bacteria that absorbs the sunlight needed for photosynthesis
