Plants and their Different Parts
Living organisms capable of synthesizing food on their own are called as plants. They contain chlorophyll, the green magnesium compound which helps in trapping the energy from sun. This energy runs the process of photosynthesis through which glucose is basically synthesized in leaves and green stems on combining together the atmospheric carbon dioxide and water.
