Hundreds of millions of years ago, algae appeared on the earth. Green algae is not much different from other algae. It does not have chlorophyll and can only rely on the external environment to absorb nutrients. Later, there were cyanobacteria in the ocean, which could absorb sunlight and release energy for their own growth. This was the earliest birth of plants. As it grows and evolves, it gradually breaks away from the ocean, and its structure gradually changes from simple to complex. Note that if it is divided through the binary realm, fungi are the first plants to be born.

1. Birth

Hundreds of millions of years ago, algae appeared on the earth. Green algae is one of them. It is not much different from other algae. It does not have chlorophyll and can only rely on Absorb nutrients from the external environment. Later, cyanobacteria appeared in the ocean, and photosynthetic bacteria appeared among them. Strictly speaking, they are the origin of plants, which can absorb sunlight and release energy for their own growth. Plants will gradually grow from simple to complex, from aquatic to terrestrial. They first appear as algae in the ocean, and as they grow and evolve, they gradually leave the ocean. Note that if it is divided through the binary realm, living things will only be divided into plants and animals, then fungi are the earliest plants. If it is divided by other methods, then the birth of the original plants is algae.

2. Evolution

Just the beginning Algae in China are only single-celled plants. After a long evolution process, they have evolved into multi-celled algae, and their growth structures have gradually become more complex. Later, due to the violent movement of the earth's crust, some original oceans evolved into land, and the algae in the ocean evolved into ferns, which could more easily adapt to the land environment. Later, because the climate on land is relatively dry, ferns will also evolve into gymnosperms, and they can completely get rid of their dependence on waters.
