Concept:Photosynthesis is the biological process where green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
Explanation:Plants absorb carbon dioxide from the air through stomata in their leaves.
Water is taken up by roots from the soil.
Sunlight provides energy that drives the reaction inside chloroplasts.
Chlorophyll, the green pigment, captures sunlight.
The reaction produces glucose (
C6H12O6) and releases oxygen as a byproduct.
Glucose is a carbohydrate that serves as the primary energy source for the plant.
Excess glucose is often stored as starch in roots, stems, and leaves.
This process occurs only in green parts of plants, mainly leaves.
Thus, plants prepare glucose exclusively through photosynthesis.
