Which natural compound helps in photosynthesis of plants?

Chlorophyll

The correct answer is Option (1) - Chlorophyll

Chlorophyll is the natural compound that plays a crucial role in the photosynthesis of plants. It is a green pigment found in the chloroplasts of plant cells and is responsible for capturing light energy from the sun. Chlorophyll absorbs light in the blue and red parts of the electromagnetic spectrum and uses this energy to convert carbon dioxide and water into glucose, a process known as photosynthesis. This glucose serves as an essential energy source for the plant, and oxygen is released as a byproduct. Curcumin and lectin are not directly involved in the photosynthesis process.
