LIFE SCIENCE

Detailed explanation-1: -The reactants of photosynthesis are carbon dioxide and water.

Detailed explanation-2: -Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants (Figure 5.5). After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose. These sugar molecules contain the energy that living things need to survive.

Detailed explanation-3: -Photosynthesis produces water as a byproduct. During photosynthesis, plants take carbon dioxide ( C O 2 ), and water ( H 2 O ) from the air and soil. In the plant cell, carbon dioxide is reduced, which results in the gain of electrons, whereas water is oxidized, which results in the loss of electrons.
