Importance
of light to plants



Sunlight acts as the ultimate source of energy for plants. Plants are
autotrophic organisms, which need light for carrying out the process of
photosynthesis. Light also plays an important role in generating photoperiodic
responses occurring in plants. Plants respond to changes in intensity of light
during various seasons to meet their photoperiodic requirements for flowering.
Light also plays an important role in aquatic habitats for vertical distribution
of plants in the sea.
