Plant

Plants are the eukaryotic organisms that constitute the kingdom Plantae. They are predominantly photosynthetic, meaning that they obtain their energy from sunlight. They do that using the green pigment chlorophyll in their chloroplasts to produce sugars from carbon dioxide and water. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular, except for some green algae.
