Plants are able to grow toward the light due to the process known as phototropism. This process takes place inside the plant. Is i Behavioral, structural, or Physiological

Physiological

Explanation:

The process whereby plants respond and grow towards light is a physiological process.

Physiological processes are life-sustaining processes that require the combined efforts of cells, tissues, organs, and or systems along with that of biomolecules in the body.

The response of plants to light requires the efforts of a hormone that triggers the rapid mitotic division of cells of tissues/organs that are directly opposite the light source. Thus, the faster rate of division of these cells as compared to the cells of tissues/organs that are directly in contact with light leads to the plant's tissues/organs bending towards the light.
