Down
- 1. first step in releasing the energy of glucose, in which a molecule of glucose is broken into two molecules of pyruvic acid
- 2. process that releases energy from food in the presence of oxygen
- 5. process that requires oxygen
- 6. organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy
- 8. a substance or molecule that participates in a chemical reaction
- 11. the main organ of photosynthesis and transpiration in higher plants
- 12. the form of sugar that circulates in the blood and provides the major source of energy for body tissues.
- 13. 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
- 16. an organ in vascular plants that anchors the plant and enables it to absorb water and minerals from the soil.
