Answer 2

The movement in any part of a plant due to light is called phototropism. The shoot of plant shows positive phototropism and roots show negative phototropism .

Phototropism in plants occurs due to the hormone auxin . When light falls on one side of a plant , the secretion of auxin hormone is more in the part away from the light . Hence , auxin causes growth in length of the cells in shady part . So the plant appears to bend towards light .
