  Previous Year Questions: 1. Bulliform cells are responsible for                                                                                              (2024) A) Inward curling of leaves in monocot B) Protecting the plant from salt stress. C) Increased photosynthesis in monocots. D) Providing large space for storage of sugar. Ans. A - Inward curling of leaves in monocot. Explanation: In grasses certain adaxial epidermal cell along the veins modify themselves into large, empty, colorless cells. These are called bulliform cells. 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 minimize water loss. 2. In the given ...
