Of these, more than 260,000 are seed plants. Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom. Most biologists also consider green algae to be plants, although others exclude all algae from the plant kingdom.

The current diversity of species is a product of the processes of extinction and speciation throughout the previous 3.8 billion year history of life. There might be 40 million species alive today, but between 5 and 50 billion species have lived at some time during the history of the Earth.
