What is the main role of chlorophyll in plant cells?

• A. To produce ATP
• B. To trap light energy
• C. To synthesize proteins
• D. To facilitate cell division

Answer: (B)

Chlorophyll's primary function in plant cells is to trap light energy, which is essential for photosynthesis. This green pigment absorbs light most efficiently in the blue and red wavelengths while reflecting green light, giving plants their characteristic color. During photosynthesis, the energy captured by chlorophyll is used to convert carbon dioxide and water into glucose and oxygen. This process is critical for the survival of plants and also provides energy for other organisms in the ecosystem through the food chain. The ability to capture light energy is fundamental to the growth and energy production in plants, making this role indispensable for their overall function and the sustenance of life on Earth.
