How does the boundary layer resistance affect the transpiration and photosynthesis compromise?
A thicker boundary layer increases transpiration and enhances CO2 diffusion.
A thicker boundary layer reduces transpiration but also limits CO2 diffusion to the leaf surface.
Boundary layer resistance has no impact on either transpiration or CO2 diffusion.
A thinner boundary layer reduces transpiration and limits CO2 diffusion.

What role do stomata play in the transpiration and photosynthesis compromise?
