It turns out plants can also reproduce through viviparity

After billions of years of evolution, animals went from fish to amphibians to reptiles and birds, and finally evolved into mammals, only then acquiring viviparity, the most "advanced" mode of reproduction. If someone told you that some plants are also viviparous, you would surely find it hard to believe. Plants reproduce the next generation either through seeds or through branches; viviparity, that "advanced method," would never be associated with plants no matter how you think about it.

On the coasts of the tropics and subtropics grows a special plant "tribe" - the mangrove forest. The plants in mangrove forests include mangrove trees, Kandelia obovata, and others, and they protect the ecological balance of coastal areas. The plants in mangrove forests all adopt a "viviparous" mode of reproduction.

After these plants' seeds mature, they do not fall off immediately but begin to germinate directly on the fruit, so green little sticks can often be seen on mangrove plants; they are the "fetuses" of mangrove trees. Only after these fetuses grow to a certain extent do they fall from the parent plant, and the process is very similar to mammalian childbirth. After these fetuses fall from the parent plant, within 12 hours they grow powerful roots and dig into the coastal mud and sand.

The reason mangrove plants evolved this reproductive method similar to viviparity is mainly related to the plants' growing environment. These plants live in salt water with a relatively high salt content, and such an environment is not favorable for seed development. At the same time, coastal areas have rising and falling tides, and seeds in such soil are also easily washed away. In order to reproduce the next generation, mangrove plants evolved this reproductive method similar to "viviparity."
