Plants need sunlight to grow and stay healthy. Through a process called photosynthesis, they turn light energy into food. Leaves act like small solar panels that catch sunlight from the sky. They also take in carbon dioxide and release fresh oxygen for us. This natural cycle is essential for all life on Earth. Without plants, it would be difficult for animals and humans to survive.
