How Do Plants Absorb Light Energy From the Sun?

Plant leaves contain chloroplasts, which have chlorophyll that absorbs light energy from the sun. Chlorophyll is the green pigment that is important for the process of photosynthesis in plants.

Chloroplasts are organelles, which are enclosed in two layers of membrane called the inner and outer membranes. Between these two membranes is an intermembrane space. Other important organelles in the chloroplast are the thylakoids. Chlorophyll is found on the thylakoids.

The photosynthesis process involves the reaction in which carbon dioxide, water and light energy from the sun are the reactants needed to produce glucose and oxygen. Photosynthesis occurs in two steps, which are the light dependent reaction and the light-independent reaction. The light-dependent reaction occurs in the thylakoids.
