Today's plants have gradually evolved from the original single-cell plants. The first single-cell plants had only one cell and had a relatively simple structure. As the external environment changed, single cells could no longer adapt to the growth environment at that time and began to evolve into multi-cells, taking on the appearance of today's plants. With development and evolution, plant structures and functions gradually become thinner, but some are still single-celled.

Today’s plants have gradually evolved from the original single-cell plants. The first single-cell plants had only one cell performing the function of growth and could grow by themselves. Survive. As the external environment changed, single cells could no longer adapt to the growth environment at that time, so they began to gradually evolve into 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 become thinner, and they have functions such as growth, flowering, and fruiting. However, some plants still retain their original single cells due to small changes in the environment. form.

2. Plant Evolution

Just It was very simple at first, just a single-celled fungus plant, without roots, stems, leaves and other organs, and without chlorophyll synthesis nutrients. As it develops, it evolves into algae. At this time, it already has chlorophyll, which can absorb sunlight and synthesize nutrients. Later, it begins to have lichen plants composed of algae and mycelium. Later, the environment changed greatly and required evolution to adapt to growth. Lichens gradually evolved into bryophytes, then into ferns, and then into the current seed plants.
