1、 Algae

In the earliest period, the primitive single celled organisms will gradually become the most primitive algae, such as green algae and cyanobacteria. These originated in water and are very dependent on water, and their growth is inseparable from water. With the evolution, the original single cell will gradually evolve into multiple cells, and the structure will gradually become more and more complex

2、 Moss

The algae in the water gradually evolved to the land and became lower mosses, such as lichens. They have a strong ability to adapt to the environment

3、 Fern

With the progress of crustal movement, some oceans would have turned into land, and the plants in the sea gradually evolved into ferns. At first, it was only an evolved naked syncope, and there were no leaves and roots. It only lived on land by relying on pseudoroots. Later, it will evolve into stems, roots and leaves, but reproduction is still inseparable from water

4、 Gymnosperms

Later, due to climate change and crustal movement, the originally growing ferns will disappear in large quantities, and the previous ferns will gradually evolve into gymnosperms. At this time, they can completely leave the influence of water and adapt to the growth on land

5、 Angiosperm

This is already the most advanced kind of plant, with real flowers
