Solution
- Sunlight acts as the ultimate source of energy for plants. Plants are autotrophic organisms that need light to carry out the process of photosynthesis.
- Light also influences chlorophyll production, the number and placement of chloroplasts, stomatal movements, metabolism, and photoperiodism.
- It also plays a vital role in generating photoperiodic responses occurring in plants and aquatic habitats for the vertical distribution of plants in the sea.
- Plants respond to changes in light intensity during various seasons to meet their photoperiodic requirements for flowering.
- Overall, light plays a crucial role in plant growth, development, and survival.
