Light is one of the important and essential variables for the process of photosynthesis that leads to plant growth.
The development of plants due to light is known as photomorphogenesis that includes several aspects of light supporting plant growth. some of them are as follows:
<u>Photodormancy</u>: it is process in which light helps plants in the germination of seeds.
<u>Phototropism:</u> This is the phenomenon in which plant bent towards the light source
<u>photosynthesis:</u> in this process light functions in the syntheiss of food for plant.
<u>photoperiodism:</u> The flowering time is based on the length of the day and night is called photoperiodism.
So, this is how light plays an important role in plant growth.
Deep ocean currents Differences in water density, resulting from the variability of water temperature (thermo) and salinity (haline), also cause ocean currents. This process is known as thermohaline circulation.
