Take a potted plant. Put it in a cardboard box and close the box. Make a hole on one side of the cardboard box in such a way that light enters only through this hole. Keep watering the plant regularly for a few days.
(a) The plant would grow upright inside the box because it is getting all the essential requirements for growth.
(b) The plant would bend towards the hole because plant responds to light.
(c) The plant would grow upright inside the box because it is not getting direct sunlight.
(d) The plant would bend towards the hole because it has to exchange gases through hole.
Correct Answer: (b) The plant would bend towards the hole because the plant responds to light.
Explanation:
The process of bending of the shoot (upper part of the plant) towards the light is known as phototropism.
