What is the relationship between the level of incident solar radiation at the leaf surface, and stomatal movements

Answer 1

There is a direct relationship between the level of incident solar radiation at the leaf surface and stomatal movements. More the surface area of the leaf more solar radiation it will absorb as it will have a number of the cell which means the number of chloroplast molecules in the overall area will more.

Light insisted is directly involved in the opening and closing of stomata. It has been found electron transport inhibitor during light reaction leads to closing of stomata. As the light intensity increase, the width of the pore of stomata also increases.
