Plants are a major group of living things including familiar organisms such as trees, flowers, herbs, bushes, grasses, vines, ferns, and mosses. About 350,000 species of plants, defined as seed plants, bryophytes, ferns and fern allies, have been estimated to exist. As of 2004, some 287,655 species had been identified, of which 258,650 are flowering and 15,000 bryophytes. Plants are mostly autotrophs, organisms that obtain energy from sunlight or organisms that make their own food. Most plants carry out a process called photosynthesis, which occurs in the chloroplasts of plants.

External distribution

Plants are distributed worldwide in varying numbers. While they inhabit a multitude of biomes and ecoregions, few can be found beyond the tundras at the northernmost regions of continental shelves. At the southern extremes, plants have adapted tenaciously to the prevailing conditions. (See Antarctic flora.)
