In the earliest period, the original single-celled organisms gradually turned into the most primitive algae. As the original single cells evolved, they gradually evolved into multi-cells. The algae in the water gradually evolved on land and turned into low-grade moss. With the movement of the earth's crust, plants in the sea gradually evolved into ferns. Afterwards, ferns will gradually evolve into gymnosperms, and then the most advanced plants, namely angiosperms, will appear.
1. Algae
1. Algae
In the earliest period, the original single-celled organisms would gradually turn into the most primitive algae, such as green algae, cyanobacteria, etc. These originated in water and were very dependent on water. , growth is also inseparable from water. With evolution, the original single cells will gradually evolve into multi-cells, and the structures will gradually become more numerous and complex.
2. Moss
In water Algae gradually evolved on land and turned into low-grade mosses, such as lichens. Their ability to adapt to the environment is very strong.
3. Ferns
As the crustal movement progresses, some oceans will turn into land, and the plants in the sea will gradually evolve into ferns. At first, it was just a nudibranch that evolved. It had no leaves or roots and only relied on rhizoids to live on land. Later, stems will evolve, as well as roots and leaves, but reproduction is still inseparable from water.
4. Gymnosperms
After Due to climate changes and movement of the earth's crust, ferns that originally grew will disappear in large numbers. The former ferns will gradually evolve into gymnosperms. At this time, they can completely escape the influence of water and adapt to growth on land.
5. Angiosperms
This is already the most advanced type of plant, with flowers in the true sense.
If you want to grow flowers at home, just choose these “3 types” and they will bloom for up to 100 d
