 It is kept in a particular vessel. From above a test tube filled with water is kept. If this apparatus is kept in light of electricity no chemical reaction takes place. But as soon as it is kept in sun light reaction commences. The plant accepts water and on the surface of the test tube filled with water, bubbles are seen.

This proves that if sun light is absent plants, trees etc cannot bloom even a wee bit. If we place a sapling in a closed box wherein sunlight does not enter it, the sapling will not grow and after becoming yellow it will wither away. But suppose it is again kept in sunlight it will start becoming green again.

This activity of photosynthesis does not only help the plant grow but that such an activity commences in the world wherein man and other creatures have the capacity to remain alive. If photosynthesis is absent man would not remain alive. The fact that sun helps plants grow and plants help mankind sustain life is very important. If it is seen at the cosmic level or it is experienced we will know that despite there being many types of life in the entire world yet the main activity is that of photosynthesis of sun light. If it were to stop life would come to a standstill on earth.

At the base of leaves lies a subtle opening called stomata. It is like a breathing apparatus and works like a kitchen. This stomata pulls within it self, air and carbon dioxide from sun light. The roots imbibe water and transport it to the leaves. Along with sun light and cholorophyll carbondioxide makes carbohydrates. This process takes place in the mesophyll area of leaves.
