What process does a plant follow in order to prepare its own food?

Photosynthesis

The correct answer is Option (3) –Photosynthesis

The process that a plant follows in order to prepare its own food is: Photosynthesis

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy stored in glucose or other organic molecules. During photosynthesis, plants use carbon dioxide and water, along with light energy absorbed by chlorophyll pigments in chloroplasts, to produce glucose and oxygen. This glucose serves as the primary energy source for the plant, while the oxygen is released into the atmosphere as a byproduct. Photosynthesis is crucial for the survival of most life forms on Earth, as it provides the foundation of the food chain by producing organic molecules that serve as food for other organisms.
