Question : Leaves of many grasses are capable of folding and unfolding because:
Option 1: their mesophylls is not differentiated into palisade and spongy parenchyma
Option 2: they have stomata on both sides of leaf
Option 3: they have high levels of silica
Option 4: they have specialized buliform cells

Correct Answer: they have specialized buliform cells

Solution : The correct option is they have specialized buliform cells.

Many grasses' leaves can fold and unfurl due to the existence of specialised cells known as "buliform cells." These cells are located in the leaf epidermis and are important for the leaf's capacity to roll or fold in response to moisture changes. Buliform cells are big, water-filled cells that alter shape depending on how much water they possess. The cells become turgid when they are hydrated and filled with water, causing the leaf to expand and flatten. The leaf folds or rolls up when the cells lose water and become flaccid. This folding and unfolding process aids grasses in conserving water during dry seasons and maximising photosynthetic exposure.
