Answer 1

Answer:

The directional movement of a plant in response to light is called phototropism. (ii) When sunlight fells on only one side of the plant, the auxin diffuses towards the shady side of shoot. ... The concentration of auxin stimulates the cells to grow longer.

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 .
