Question

The main difference between photosynthetic and chemosynthetic bacteria is that:

• A. Water is used by photosynthetic bacteria whereas it is rejected by chemosynthetic bacteria
• B. Photosynthetic bacteria are seen as parasites within green plant cells whereas chemosynthetic bacteria are seen as saprophytes on other decaying food substances
• C. Photosynthetic bacteria are seen in green plants whereas chemosynthetic bacteria are seen in chemical substance
• D. Energy from sunlight is used in photosynthetic bacteria while in chemosynthetic bacteria energy is used by the oxidation of inorganic substances

Answer 1

The correct option is D Energy from sunlight is used in photosynthetic bacteria while in chemosynthetic bacteria energy is used by the oxidation of inorganic substances

The main difference between photosynthetic and chemosynthetic bacteria is from where they get the energy for synthesizing food. Energy from sunlight is used in photosynthetic bacteria whereas in chemosynthetic bacteria energy is derived by the oxidation of inorganic substances.
