People want face, trees want skin. How important is bark to trees?

As an important part of trees, bark plays a very important role. It can not only protect trees, but also provide them with nutrition.

First of all, no matter what tree species have their own bark, and bark plays a very important role in trees. Bark is like the armor of the trunk, protecting the trunk. This protective effect is mainly reflected in preventing some pests from destroying the inside of the trunk. Because the appearance of bark is generally rough, it can prevent pests from causing diseases to trees to a certain extent, just like the natural protection of trunk. In addition, the existence of bark can also play a certain role in keeping warm, because the growth of trees is directly related to the climate. Generally speaking, we can see that the bark is relatively thick in cold areas, and the most important function of this is that the bark can play a good role in keeping warm and prevent the trunk from dying because of the cold weather.

In addition, the most important function of bark is that it can provide nutrients for the growth of trees today. Bark, as the outermost tissue of the trunk, is also different. Generally speaking, the rough bark is dead cell tissue, indicating that this part has no vitality. The other part is inside this layer of bark, and there is a layer of living bark. It is precisely because of the existence of this part of bark that it provides nourishment for the growth of trees. Under photosynthesis, leaves will produce certain nutrients, which are found in bark? Phloem tissue? To transfer nutrients, and in the growth process of a large number of trees, it is precisely because bark has the function of transferring nutrients that the normal growth of trees can be guaranteed.

It can also be seen that a tree without bark is difficult to ensure normal growth. On the one hand, bark can prevent external damage to trees, on the other hand, bark can provide needed nutrients for trees.
