Light is sn important element in the growth of a plant.
Explanation:
Light is an important factor influencing plant growth. It is a common observation that plants grow towards light. Charles Darwin and his son Francis Darwin first observed that the coleoptiles of canary grass responded to unilateral illumination by growing towards the light source (phototropism). After a series of experiments, it was concluded that the tip of coleoptile was the site of transmittable influence that caused the bending of the entire coleoptile due to more growth on the dark side. That transmittable influence is now thought to be the phytohormone called auxin.
