Trees, such as some animals in spring and summer in the body stores energy and nutrients, in winter, they go through the rest process. In spring and summer, it converts sunlight into energy by photosynthesis in plants and trees. In the structure of all plants, there are various pigments that give color.
Chlorophyll pigment that gives green color to the leaves is a chemical compound that allows photosynthesis to take place. However, in autumn and winter, there is not enough light and water for photosynthesis to occur, so the number of chlorophyll in the leaves is reduced and other color pigments are exposed.
They give yellow color to the leaves xanthophyll, orange color giving the carotid and red color of the anthocyanidindir. All these color pigments are constantly present on all leaves, but the chlorophyll that gives the green color is dominant because the leaves are in green color.
