Vegetation Transformation

The video explains how plants perform photosynthesis, a process that converts light energy into chemical energy in the form of sugar. Chlorophyll in plant cells captures sunlight, enabling the transformation of water and carbon dioxide into sugar and oxygen. An experiment demonstrates the necessity of light for photosynthesis, showing that plants deprived of light cannot produce energy. The video highlights the importance of photosynthesis for oxygen production and as a source of energy for animals.
