Why are the trees evergreen all year round, and what trees are evergreen all year round

The leaves are small and the water does not evaporate easily.

Pine and cypress trees are originally trees that grow in the cold zone and high mountains, and they have formed a unique structure to protect them from the cold because they have lived in a cold environment for a long time. The leaves of pine and cypress trees are generally shrunk to needle-shaped, linear or scaly-shaped, and due to the small leaf area, water is not easy to evaporate and dissipate. Some leaves are thick or waxy, while others have thick hairs.

If you take a pine leaf and look closely, you can see that it is densely covered with white hairs, which feel smooth to the touch, and these structures effectively prevent the evaporation of water. At the same time, the leaves of pine and cypress trees have less water and contain pine resin, which can quickly increase the concentration of cell fluid when the temperature drops, and increase sugar and fat in order to prevent freezing. Therefore, even in winter, the pine and cypress trees will not dry out due to lack of water, ensuring that the vitality of the trees will last forever.

The leaves on trees have a certain life period, and the length of life varies from plant to plant. Every leaf falls off when it reaches a certain age, and pine and cypress trees are no exception. Its leaves are also to decline, but the leaves of the pine and cypress tree have a long life period, can live for 3 5 years, and when they are replaced, they are alternate with each other, generally after the new leaves occur, the old leaves are then withered, and the whole tree seems to be not deciduous as if it does not fall leaves, so it makes people have the feeling of being evergreen in winter and summer.

Although the leaves of the pine and cypress trees are still green in winter, they are much less colorful than in spring, summer, and autumn. This is due to the low temperature in winter, the production of chlorophyll in the leaves is limited, and the anthocyanins are relatively increased, so the leaves are a little red. This color change can weaken the photosynthesis in the leaves, making the physiological activity of the tree slow.

This is very beneficial to ensure that the pine and cypress trees survive the winter safely.

Because its genes are evergreen.
