STUDY OF PHOTOTROPISM AND GEOTROPISM IN PLANTS
In this video we will see the mechanism known as phototropism and geotropism which causes plants to bend towards the light. The plants need light to promote the process of photosynthesis, which produces energy. A hormone called auxin, which responds to phototropism, is present in the plant cells that are furthest away from the light this causes the plant to have elongated cells on the furthest side from the light.
Almost all plants respond to photosynthesis in order to get more nutrition and energy. The stem and shoots usually react to positive phototropism by turning towards the sunlight, while negative phototropism takes place in the roots which turn away from the source of light. Here gravitropism or geotropism plays a major role in their growth. Positive geotropism is the movement of plant parts in the direction of the gravitational attraction, whereas negative geotropism is the movement of plant parts in the direction of the gravitational pull. Moreover, the root geotropism provides multiple advantages to a plant's vitality and survival.
