Cellular Respiration and Photosynthesis

Describe the role of chlorophyll in the process of photosynthesis.

• It absorbs carbon dioxide from the atmosphere.

• It absorbs light energy to convert it into chemical energy and gives the leaves pigment

• It releases oxygen as a byproduct and green

• It breaks down glucose to release energy.
