How does cactus adapt to desert arid environment

Cactus can still survive in the desert environment with extreme water shortage. A large part of the reason is that its structure can well lock in the water. Moreover, its root system is very developed. When it is short of water, it will extend downward until it finds the water source. Of course, if the environment is very bad, the plant will wither and die.

The result of evolution

1. We all know that the water shortage of the plant is due to the stomata on the surface of the leaves, which will take away a lot of water during transpiration, while the leaves of cactus plants have already become prickles, so there will be no water evaporation. At this point, the water of the plant can be reserved to maintain life activities.

2. Another very important reason is that the surface of the plant has a strong keratinization, just like a layer of wax, and the stomata sinks, so that the plant's water will be deeply locked in the cell, sometimes the water stored by itself can reach 95% of its weight, which can be seen in the desert to maintain life or

Second, its own advantages

1. When it comes to its own advantages, it refers to the root of the plant, which has a very strong ability to absorb water. Even the water in the air can be collected for its own use to a certain extent.

2. If the plant is short of water and the root system has no water to absorb, it will continue to extend until the water source is found again, so the plant can grow in such a bad environment.
