Photosynthesis
1. Occurs only in green plants or chlorophyllated organisms.
2. Sunlight or solar energy is essential.
3. Involves pigment systems to trap solar energy.
4. Radiant energy is fixed as chemical energy and stored in organic molecules like carbohydrates.
5. Oxygen is evolved during the process.
6.Major contribution of energy to the total biospheric energy reserve.
Chemosynthesis
1. Occurs only in some chemosynthetic bacteria.
2. Sunlight or solar energy is not essential.
3. Pigment systems are not necessary.
4. Chemical energy is released by the oxidation of inorganic molecules and is then stored in organic molecules.
5. Oxygen is not evolved during the process.
6. No significant contribution of energy to the total biospheric energy reserve.
