Across
- 2. The green pigment in chloroplasts that captures sunlight for photosynthesis.
- 5. A gas released during photosynthesis and required for cellular respiration.
- 6. An organism that obtains energy by consuming other organisms.
- 8. The organelle in cells where cellular respiration takes place, producing ATP.
- 12. A simple sugar (C6H12O6) that serves as the primary energy source for cellular activities.
- 14. Respiration The process by which cells break down glucose and oxygen to produce energy (ATP), carbon dioxide, and water.
- 15. The process by which plants, algae, and some bacteria convert light energy, water, and carbon dioxide into glucose and oxygen.
- 16. Respiration A type of cellular respiration that does not require oxygen, resulting in less energy production.
- 18. Energy Energy from the sun, which is converted into chemical energy during photosynthesis.
- 19. Dioxide A gas used by plants during photosynthesis and produced as a waste product during cellular respiration.
- 20. The sum of all chemical reactions in an organism, including energy conversion processes.
Down
- 1. Tiny openings on the surface of leaves that allow gas exchange (CO2 in, O2 out).
- 3. The substances (e.g., glucose and oxygen) formed during a chemical reaction like photosynthesis.
- 4. The organelle in plant cells where photosynthesis occurs.
- 7. An organism that can produce its own food through photosynthesis.
- 9. Respiration A type of cellular respiration that requires oxygen to produce energy.
- 10. The substances (e.g., carbon dioxide and water) used in a chemical reaction like photosynthesis.
- 11. (Adenosine Triphosphate) The molecule that stores and provides energy for cellular processes.
- 13. Energy Energy stored in the bonds of molecules like glucose.
- 17. Conversion The process of changing one form of energy (e.g., light energy) into another form (e.g., chemical energy).
