A growing seedling is kept in a dark room. A burning candle is placed near it for a few days. The top part of seedling bends towards the burning candle. This is an example of:(a) chemotropism (b) hydrotropism (c) phototropism (d) geotropism
(c) Phototropism.
The process of bending of the shoot (upper part of the plant) towards the light is known as phototropism.
