Etiolation is caused by the influence of

Etiolation is caused by the influence of the absence of light. Etiolation is a phenomenon that occurs in plants when they are grown in the absence of light or insufficient light. When a plant is deprived of light, it will begin to elongate rapidly and become pale in color. This is because light is essential for the process of photosynthesis, which produces energy for the plant to grow and develop. In the absence of light, the plant cannot produce chlorophyll, the green pigment that absorbs light and is necessary for photosynthesis to occur. As a result, the plant will grow tall and spindly in search of light, and its leaves will become thin and pale. This process of elongation and pale coloration is known as etiolation. So, in summary, etiolation is caused by the influence of the absence of light, which prevents the plant from producing chlorophyll and carrying out photosynthesis.
