Photosynthesis

Plants are unique as they produce their own food through photosynthesis, a process that converts sunlight into energy. This energy is stored and used for growth. Photosynthesis involves light and dark reactions, producing ATP and glucose. Chlorophyll in chloroplasts gives plants their green color by reflecting green light. Plant stems play a crucial role in transporting water and nutrients and providing support. Some plants, like cacti, have adapted to store water in their stems. Overall, plants are essential producers for all life on Earth.
