Answer:
It helps in the synthesis of carbohydrates that serves as food for the entire plant by a process called PHOTOSYNTHESIS.
Step-by-step explanation:
Chlorophyll's job in a plant is to absorb light i.e usually sunlight. The energy absorbed from light is transferred to two kinds of energy-storing molecules. Through photosynthesis, the plant uses the stored energy to convert carbon dioxide (absorbed from the air) and water into glucose i.e a type of sugar molecules need in plants.
Chlorophyll is found in virtually all photosynthetic organisms, including green plants, cyanobacteria, and algae.
