Why Does the Sunflower Change its Direction towards Sunlight?
Plants prepare starch with the help of carbon dioxide which is present in the sunlight and this is done through photosynthesis. Photosynthesis process in the sunflower is related to sun. In order to carry the photosynthesis process easily, the buds of the sunflower move in the direction of the sun. In this way, the sunflower moves in the east direction which is the direction of the sun. Oxyne hormone which grows on the sunflower is responsible for this movement. Sunflower turns in the direction in which the oxyne is present in more amounts and it is more in the direction of the sun as it gets more sunlight. In the evenings, sunflower turns to the west direction as the oxyne is present in more amounts in that direction. Even after the sunset, sunflower moves in the direction of east at the night. In the next morning, the process is same and it moves in the direction of the sun. After extracting the oil from the seeds of sunflower, the waste material is used as fuel in the boilers and other places. Sunflower is used for painting, preparing the medicines and it is also food for the birds.
