Read the following statements regarding leaf anatomy: Statement A: In grasses, certain adaxial epidermal cells modify into large, empty, colourless cells. Statement B: When bulliform cells are turgid, they make the leaf curl inwards. Statement C: Bulliform cells are absent in dorsiventral leaves. Statement D: In an isobilateral leaf, the vascular bundles are nearly similar in size, except in main veins. How many of t

Step-by-step solution

Statement A is correct as in grasses, certain adaxial epidermal cells along the veins modify themselves into large, empty, colourless cells called bulliform cells. Statement B is incorrect because when bulliform cells are turgid, the leaf surface is exposed. They make the leaves curl inwards to minimise water loss only when they become flaccid due to water stress. Statement C is correct as bulliform cells are a characteristic feature of isobilateral (monocot) leaves, such as grasses, and are absent in dorsiventral
