Where they live: Plants are found on every continent, even Antarctica, and every ocean.
What they eat: Plants use sunlight for photosynthesis, which produces sugars that fuel them.
How big they are: The smallest plants, known as desmids and picozoa, are single-celled algae that are less than 0.0004 inches (0.01 millimeters) across. The largest plant is Pando, an enormous tree network in Utah that's 106 acres (43 hectares) — about the size of 80 American football fields.
Plants are an incredibly diverse group of organisms, ranging from tiny algae to majestic redwood trees. Plants have colonized nearly every environment on Earth, evolving ways to thrive in blistering deserts, salty coastlines and dripping rainforests. They support most life on Earth because they sit at the base of almost every food chain and pump out the oxygen we need to breathe.
