Understanding Photosynthesis

The video explains photosynthesis, a process by which plants make their own food using sunlight, chlorophyll, carbon dioxide, and water. Chlorophyll in leaves absorbs sunlight, enabling the plant to convert carbon dioxide and water into sugar and oxygen. The sugar is used for growth and energy, while oxygen is released. The video details the roles of chlorophyll, stomata, and plant roots in this process.

What is the primary process through which plants produce their own food?
