Plants were the first multicellular organisms to colonise the land, changing the atmosphere of earth and paving the way for animals to move out of the seas.
Land plants have existed for about 450 million years. In order to survive out of the water plants had to develop specialised structures and anatomy to enable them to absorb water, nutrients and energy so that they could grow and reproduce.
Flowering plants first appeared about 180 million years ago. Today, 90% of the plant kingdom are flowering species, while algae, conifers, ferns, horsetails, mosses, liverworts, and their relatives, make up the remaining 10%.
