This lead to life beginning in the ocean where it was safe from the suns rays. It was here that life began with bacteria and small microscopic plants, called algae. Algae is the mankinds oldest known fossil. Found in rocks of mho Africa and Central Australia up to 3100 years ago. The bestride of Algae lasted more than 2000 million years old, which is about half of planet earths lifetime. During this tenacious period of time, some of the algae positive the ability of world able to make food by using the muscularity from sunlight to converts carbon dioxide and water into sugar or starch. This traveling bag out was called photosynthesis. The conterminous stage in the development in plants was The season of Primitive Vascular Plants. This new p eriod (the sulphur stage) in plant bill occurred within the next 50 million years (400-500 million years ago). Some of these developed simmer down systems stems and leaves. They also formed woody tissue, which created stiffer stems, which at last developed into direct trunks. They became tree-like and up to 40 meters tall, forming the worlds first forest.

The Age of Seed tutelage Plants was the next stage of plant history where plants were taken to their next step up in the evolution. This occurred roughly 280 million years ago. This was also the dinosaur era. Earth began to become a lot drier, and these plants began to suit to the ever so changing climate.
