The video explains how plants make their own food through photosynthesis, a process that converts light energy into chemical energy. It details the essential factors required, such as sunlight, water, and carbon dioxide, and describes the role of xylem and stomata in transporting nutrients and gases. The process involves chloroplasts converting carbon dioxide and water into glucose and oxygen. Variations like underwater photosynthesis and exceptions like mushrooms and venus fly traps are also discussed.
