Question

what happens when a growing plant detect light? explain in brief ​

Answer 1

The bending of plant towards light is known as phototropism. It is due toplant hormone auxins. When thegrowing parts of a phototropic plant detect sunlight, auxins (synthesized at the shoot tips) help the cells growlonger. ... This results in the curvature of the plant stem tip towards the light

Answer 2

when a rowing plant detects light, the auxins in the plant show cell elongation on the side without light. so, the plant moves toward the light. this is called phototropic movement by the plant.

auxins are plant hormones that are responsible for elongation of cells.
