Effects of Light on Plants...!!!

 

Light exerts a significant influence on the vital physiological processes going on in the plants and their forms and structure.

Effects of light on physiological process-- the process of photosynthesis growth development transpiration and a number of metabolic process of profoundly influenced by light.


Chlorophyll and photosynthesis-- chlorophyll developed from the proto chlorophyll when the latter is exposed to light. Light intensity plays a key role in influencing photosynthesis.

Transpiration--- light influences rate of transpiration light is absorbed by a leaf raising its temperature and thus increasing transpiration and water loss. Light also plays a significant role in opening and closing of stomata.


Photomorphogenesis----the effect of light on the certain developmental reproductive and physiological functions apart from photosynthesis is known as photo morphogenesis.


Photoperiodism or duration of light--- duration of flight airport of period is the number of hours in a day during which a plant is exposed to sunlight.

1) short day plants these will flower if the light exposes is less than critical length about 14 hours.

2) long day plants these are in insensitive to day length and will bloom regardless of photoperiod.
