التركيب والوظيفة في الكائنات الحية: أهمية عملية البناء الضوئى

The video explains how plants produce their food through photosynthesis. It details the role of chloroplasts in absorbing sunlight, the absorption of carbon dioxide through leaves, and water and minerals through roots. The process results in the production of sugars and starches, which serve as food for the plant, and the release of oxygen. The video concludes with a summary of the entire photosynthesis process.
