Visual lesson 06

Leaf temperature vs air temperature

Compare measured leaf and air temperatures and connect their difference to radiation, airflow, transpiration, humidity, and the vapor-pressure gradient at the leaf surface.

Primary visual specification

Leaf-versus-air temperature and vapor-pressure comparison

Create an academically accurate leaf-versus-air temperature and vapor-pressure comparison for the Leaf temperature vs air temperature lesson. Use neutral studio lighting or clean academic illustration conventions, realistic botanical proportions, readable labels where needed, no yellow cast, and no decorative elements that compete with the teaching objective.

Practice

When estimating plant-level vapor-pressure conditions, why is measured leaf temperature often more informative than assuming it equals air temperature?
