Leena wanted to study about the growth of plants and decided to conduct a simple experiment. She took a closed cardboard box with a hole on one side and kept a little pot of plant in it. She kept this set up near a window in her room with access to sunlight. After some days, she saw that the stem of the plant is bending (almost reaching) towards the hole in the cardboard, from which the sunlight comes. What is the name of the phenomenon observed here, by which the plant responds to sunlight? |
