Starch grains will always appear white due to the
osmium tetroxide only binds to lipids.

photosynthesis
Large Surface area Capture as much light as
possible
Thin Light penetrates all the way
through the leaf
Stomatal pores Allow CO2 to diffuse into the
leaf
Air spaces in spongy Allow CO2 to get into
mesophyll photosynthesising cells
Spaces between the palisade Allow CO2 to get into
cells photosynthesising cells
Cuticle and epidermis is Light penetrates through the
transparent mesophyll
Palisades have a large Chloroplasts from a single
vacuole layer so they don’t shade
each other.
