You must have often noticed that when it is summer, the leaves of the trees standing in the scorching sun fall less, even in the spring season the trees look green and beautiful, but when the autumn season comes in the winter itself, the leaves start falling from the trees automatically. At this time there is neither extreme heat nor severe cold. Then why does this happen, have you ever thought? Let’s find out today.
Why do leaves start falling from trees in winter?
Actually, the falling of leaves is a seasonal cycle for trees. Just as we humans and animals need energy to survive, trees also go through the process of conserving light to conserve their energy and survive. Only green leaves can do this light conservation.
Trees with the help of chlorophyll present in them–Plants absorb sunlight and convert water and carbon dioxide into sugars
This is the most important element for trees
Let us tell you that chlorophyll is very important for plants, so the tree–Plants make full use of this and convert chlorophyll into smaller–Transformed into smaller molecules and stored in the stems and roots. Apart from chlorophyll, red and yellow pigments are also found in the leaves of trees, But in spring and summer, chlorophyll becomes dominant over both these colours
Due to which only green color is visible in spring and summer season whereas in October–In the month of November, chlorophyll starts moving towards the stem and roots and yellow, Red color starts appearing in front, Just as chlorophyll makes the leaves green, similarly carotenoids make the leaves appear orange and golden in colour and anthocyanin makes the leaves appear red and pink. . In such a situation, trees stop this process in winter. While on one hand the days start getting shorter before the winters arrive, on the other hand during this time the trees–During this time, plants also start preparing themselves fully to fight autumn and thus leaves fall from the trees in autumn.
