Photosynthesis and Respiration

Photosynthesis

• Transformation of radiant energy into chemical energy
• Plants accomplish this with photosynthetic pigments, e.g. chlorophyll
• Combines radiant energy, carbon dioxide, and water to produce glucose, liberating oxygen

Aerobic Respiration

• Releases chemical energy stored by plants, turns it into kinetic energy
• Both plants and animals respire
• Breaks down glucose with water and oxygen to release energy, liberating carbon dioxide
• Not all respiration is aerobic
