Plants also have viviparous reproduction.
After hundreds of millions of years of evolution, from fish to amphibians to reptiles and birds, and finally to mammals, animals have acquired viviparity, the most "high-end" way of reproduction. If there are viviparous plants, you will find it hard to believe. Plants reproduce their offspring either through seeds or branches, and the "high-end way" of viviparity will not be associated with plants.
Along the coast of the tropics and subtropics, there is a special plant "tribe"-mangroves. The plants in the mangroves are mangroves, Kandelia Candel and so on, which protect the ecological balance of the coastal areas. The plants in the mangroves all adopt the "viviparous" mode of reproduction.
The seeds of these plants do not fall off immediately after maturity, but begin to sprout directly on the fruit, so some small green sticks can often be seen on mangrove plants, which are the "fetuses" of mangroves. When these fetuses grow to a certain extent, they fall off from the mother, much like a mammal giving birth. After these fetuses fall off from the mother, they will grow strong roots within 12 hours and sink into the sand on the coast.
The reason why mangrove plants evolved this viviparous mode of reproduction is mainly related to the growing environment of the plants. These plants live in salt water with high salt content, which is not conducive to the development of seeds. At the same time, with the ebb and flow of tides in coastal areas, seeds are easily washed away in such soil. In order to reproduce the next generation, mangrove plants have evolved this "viviparous" mode of reproduction.
