1 Answer

Answer :

: Phototropic movement is a type of curvature of plants. The movement of the stems and branches of the plant is always towards the light and the movement of the roots is always against the light. The movement of the stem towards the light is called positive phototropic motion and the movement in the opposite direction of the original light is called negative phototropic motion.

Last Answer : (1) Auxin Explanation: Phototropism is the growth of organisms in response to light. In plants, phototropism is a response to blue wavelengths of light and is caused by a redistribution of auxin from ... in quicker growth on the darker side and bending of the shoot toward the source of light.

Stern is usually - (1) Positively Phototropic (2) Negatively Phototropic (3) Negatively geotropic (4) Positively acrotropic

Last Answer : (1) Positively Phototropic Explanation: Tropism is a growth movement whose direction is determined by the direction from which the stimulus strikes the plant. Most stems are positively phototropic, while most roots are said to be negatively phototropic.
