Document Summary

Boundary layer of leaf (underside) is very important to co2 intake and h2o and oxygen release. Stomata which can be open or closed at different times of day dependent on the type of plant: monocot. Not much organization in side the leaf: dicot. Well organized palisade and mesophyll layers: conifers. Stomata consistent with stomata in normal leaves: age of leaves. Older leaves have greater support structure, less nitrogen, less. Pretty dramatic difference between leaves a few months old versus older leaves why deciduous trees shed. Exponential decrease in photosynthetic capability: leaf optics: reflection and surfaces. The smoother the leaf surface, the more parallel light will reflect. The bumpier the leaf, the more random the light will reflect. The amount of cuticle on top of the leaf is usually related to the smoothness: leaf optics: packaging and scattering. Absorbed some photons are absorbed by chloroplasts. Transmitted some photons not absorbed and then are dispersed through other side of leaf.
