Solution
The correct option is A Leaves
Photoperiodism is defined as the response by an organism to the lengths of day and night.
It has been observed that a lot of plants need periodic exposure to light to induce flowering.
Leaves are considered to be the site of perception for photoperiodic stimulation.
It is the shoot apices of plants that modify themselves to flowering apices just before flowering. But these shoot apices do not perceive photoperiod by themselves. It is believed that florigen hormone produced in the leaves is responsible for inducing flowering in plants. It is transported from the leaves to the shoot apices once the plant is exposed to adequate inductive photoperiod.
