How did plants come from?

1. How did it come about?

Today's plants have gradually evolved and developed from the original single-celled plants. At the beginning, single-celled plants had only one cell to perform the function of growth and could survive on their own. As the external environment changed, single-celled organisms could no longer adapt to the growth environment at the time, so they began to gradually evolve and became multicellular plants, which basically took on the appearance of today's plants. In the process of continuous evolution and development, the structure and function of each cell in multicellular plants gradually became more refined, and they had functions such as growth, flowering, and fruiting. However, some plants still retain their original single-cell form because of small environmental changes.

2. Plant Evolution

At the beginning it was very simple, just a single-celled fungus, without organs such as roots, stems, leaves, and chlorophyll to synthesize nutrients. As they developed, they evolved into algae plants, which already had chlorophyll and could absorb sunlight to synthesize nutrients. Later, lichens composed of algae and hyphae began to appear. After that, the environment changed greatly and evolution was needed to adapt to growth. Lichens gradually evolved into mosses, and later into ferns, and then into the current seed plants.
