Statement-I : Leaf surface is exposed when bulliform cells in leaves have absorbed water and are turgid.
Statement-II : In leaf palisade parenchyma is on abaxial surface and spongy parenchyma is towards adaxial surface.
In the light of the above statements, choose the correct answer from the options given below :

Conceptual

When the bulliform cells in the leaves have absorbed water and are turgid, the leaf surface is exposed. When they are flaccid due to water stress, they make the leaves curl inwards to minimise water loss

The vertical section of a dorsiventral leaf through the lamina shows three main parts, namely, epidermis, mesophyll and vascular system.Mesophyll, which possesses chloroplasts and carry out photosynthesis, is made up of parenchyma. It has two types of cells – the palisade parenchyma and the spongy parenchyma. The adaxially placed palisade parenchyma is made up of elongated cells, which are arranged vertically and parallel to each other.
