Question

what changes occur in the leaf of desert​

Answer 1

In deserts, plant water loss from leaves is exacerbated by high water vapor pressure differences (VPD) between the leaf and the air. When water is abundant, as during the growing period for annuals, the water lost via transpiration may be inconsequential, especially compared to its role in reducing leaf temperatures.
