Plant evolution
About two billion years ago, the very first plants appeared on the planet in the form of minute organisms that inhabited the sea.
The first plants were blue green algae, and took another 1,400,000,000 years to establish themselves at least partly on land .
The first plants were the ancestors of mosses, hornworts, and liverworts , and were very short. Slowly, plants grew in height to become as large as today's massive ferns. Next, seed bearing plants evolved , forming huge Forest. The next major step in the evolutionary history of plants was much later , when flowering plants known as angiosperms first emerged.
