विकल्प

• heat to chemical

• chemical to light

• light to chemical

• chemical to heat

Answer 1

The energy transformation taking place during photosynthesis in plants is light to chemical.

Explanation:

Photosynthesis is a biological process employed by plants, algae, and certain microorganisms to transform light energy into chemical energy. In this mechanism, plants absorb sunlight (light energy) through chlorophyll, a green pigment located in chloroplasts.

The absorbed light energy is utilised to transform carbon dioxide (CO₂) and water (H₂O) into glucose (C₆H₁₂O₆), a sugar molecule that retains energy in its chemical bonds (chemical energy), along with oxygen (O₂) as a byproduct. The comprehensive chemical equation for photosynthesis is:

\[\ce{6CO2 + 6H2O + Light energy -> C6H12O6 + 6O2}\]

Thus, the fundamental energy transformation is from light energy to chemical energy.
