Photosynthesis Concepts and Processes

The video tutorial explains the process of food preparation in plant leaves, known as photosynthesis. It describes how leaves, the food factories of plants, require water, carbon dioxide, and sunlight to produce food. Water is absorbed from the soil by roots, carbon dioxide is taken from the air through stomata, and sunlight is captured by chlorophyll. These ingredients are used to convert water and carbon dioxide into food and oxygen, which is released into the air. The term 'photosynthesis' is derived from 'photo' meaning light and 'synthesis' meaning putting together.
