Plants are living organisms that obtain most of their energy from sunlight, via photosynthesis. The chloroplasts necessary for this give them their green color. Seaweed (which is a form of algae) , fungi, and bacteria are not plants. In traditional forms of classification, however, all living things fall into one of two categories: plants or animals. There are about 300.000-315.000 species of plants.
