Description : Leaves of many grasses are capable of folding and unfolding because (1) their mesophyll is not differentiated into palisade and spongy parenchyma (2) they have stomata on both sides of the leaf (3) they have high levels of silica (4) they have specialised bulliform cells
Last Answer : (4) they have specialised bulli-form cells Explanation: Bulliform cells are large, bubbleshaped epidermal cells that occur in groups on the upper surface of the leaves of many grasses. These cells, by their turgor changes, cause rolling and unrolling of the leaves thus regulating water loss.
Description : Grass leaves curl inwards during very dry weather. Select the most appropriate reason from the following. (a) Tyloses in vessels (b) Closure of stomata (c) Flaccidity of bulliform cells (d) Shrinkage of air spaces in spongy mesophyll
Last Answer : (c) Flaccidity of bulliform cells
Last Answer : they have specialised bulliform cells

Description : What are bulliform cells? What is their role?
Last Answer : Ans: Specialised larger epidermal cells seen in the upper epidermis of grass leaves which store water are called as bulliform cells or motor cells. They help in rolling and unrolling of lamina.
