During intense winters, plants and trees go into a dormancy a period of stagnation. They withdraw the chlorophyll -a pigment responsible for green colour and a must for photosynthesis– from the leaves because they know that Sun is not going to come up strongly for photosynthesis to happen and food making process to start. The leaves change color to yellow, orange and mixture of these colors. Because besides chlorophyll which overpowers the colors of other pigments there are Xanthophylls which are yellow pigments, and carotenoids (the pigment which imparts the beautiful color to carrots, papaya, and mangoes and so on) which give leaves an orange color.
Slowly the leaves die and begin falling down. The tree branches become nude. But tree is not dead. It is waiting patiently for the tough time of winter to be over. As soon as the winter starts receding, the new leaves begin coming forth. The new beginning of life. At first, due to the absence of chlorophyll, the color of other pigments shine. Leaves are beautiful translucent. As the sun starts coming regularly with renewed force, chlorophyll starts building up masking the color of other pigments. Soon the leaves become intense green shade.
Thus the the new leaves are a symbol of Spring and new hope of brighter future. Let us hope and pray to God this also happens to the world….
