Answer:
Pigment molecules absorb light energy.
Step-by-step explanation:
During photosynthesis, green plants manufacture their food when carbondioxide combines with water in the presence of sunlight. The sunlight posses heat energy which is absorbed by the green pigment in leaves called chlorophyll. Chlorophyll absorbs sunlight which converts the raw materials of photosynthesis into chemical energy products.
The green pigment in leaves helps traps and absorb sunlight which is used to drive the photosynthetic process.
