Practice questions testing deep understanding of stomatal mechanics, factors affecting transpiration, and its significance.
Q1. On a hot, dry, and windy afternoon, a plant's stomata close tightly, even though there is plenty of sunlight for photosynthesis. Explain the biological survival strategy behind this action.
Q2. Assertion (A): Most of the transpiration in a broad-leaved plant occurs through the lower surface of the leaf. Reason (R): The lower surface of a typical dicot leaf contains a significantly higher number of stomata compared to the upper surface, which is directly exposed to the hot sun.
