A young green plant was kept such that it receives sunlight from one direction only. What will be the consequence of it on shoots and roots?

Answer :

The sunlight has a different effect on the shoots and roots of the plant.

The consequence of sunlight on the shoot-


The sunlight acts as a stimulus. In this case either the movement will be in the direction of sunlight or away from it.


If the green plant is kept in sunlight from one direction, here the movement of the plant part will be in the direction of sunlight. Hence, the shoots will bend in the direction of the sunlight.


The consequence of sunlight on root-


The sunlight acts as a stimulus. In this case either the movement will be in the direction of sunlight or away from it.
