Description : How does phototropism occur in plants? -Biology-10
Last Answer : Phototropism is a growth movement induced by a light stimulus. Growth towards a source of light is called positive phototropism, that away from the source is termed negative phototropism. The tips of shoots ... that the tip was, in some way, communicating with the cells of the region of elongation.
Description : How does phototropism occur in plants ? -Biology-10
Last Answer : 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 ... in length of the cells in shady part. So, the plant appears to bend towards light.

Description : Which hormones are responsible for phototropism? -Biology
Last Answer : Growth curvature response of plants towards light is known as phototropism which is mediated by auxins in plants.
Description : What is Negative Phototropism ?
Last Answer : : Phototropism is a type of curvature of plants. The stems and branches of the plant always move towards the ala and the roots always move in the opposite direction to the ala. In contrast to Ala, the movement of the root is called negative phototropic pism .
