All of our energy for growth, development and physical activity comes from eating food from plants and animals. Photosynthesis is the process that enables plants to get energy from the sun. Kids learn about the science of photosynthesis. Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive. Carbon dioxide, water and light are all needed for photosynthesis to take place. Light-dependent reactions need light to work; and light-independent reactions, which do not need light to work. Photosynthesis is so essential to life on earth that most living organisms, including humans, cannot survive without it. Photosynthesis has two main sets of reactions. Photosynthesis is one of the most crucial life processes on the Earth. In the following article, we will try to simplify the complex process to make it easier for you kids to understand. Chlorophyll gives plants their green colour. Light energy from the sun is converted into chemical energy by chlorophyll. Photosynthesis takes place in chloroplasts, cells found in the leaves of a plant. How plants gather energy from the sun by turning sunlight, water, and carbon dioxide into glucose and oxygen using chlorophyll. It is not just important for plants, which depend on it for their food, but is equally important for humans. Interactive Photosynthesis is the process in which green plants use sunlight to make their own food. Photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds. Without it there would be no green plants, and without green plants there would be no animals. Photosynthesis is necessary for life on Earth. Photosynthesis Facts For Kids.
