**Step-by-Step Solution:** 1. **Understanding the Leaf Structure**: The leaf has two surfaces - the upper surface (adaxial) and the lower surface (abaxial). Each surface has different adaptations for their functions. 2. **Presence of Stomata**: The lower surface of the leaf typically contains a higher number of stomata compared to the upper surface. Stomata are small openings that allow for gas exchange (CO2 in, O2 out) and transpiration (water vapor loss). 3. **Reason for More Stomata on the Lower Surface**: The upper surface of the leaf is more exposed to sunlight. To minimize water loss through transpiration, plants tend to have fewer stomata on the upper surface. This adaptation helps in conserving water. ...
