Plants are living organisms that play a vital role in supporting life on Earth. They produce oxygen through photosynthesis, a process where they convert sunlight, carbon dioxide, and water into energy. Plants provide food, shelter, and medicine for humans and animals. They also help maintain environmental balance by reducing carbon dioxide and preventing soil erosion. There are many types of plants, including trees, shrubs, herbs, grasses, and aquatic plants. Found almost everywhere—from deserts to rainforests—they are essential to ecosystems. Whether growing in the wild or cultivated by humans, plants are fundamental to sustaining life and maintaining the planet’s health.
