outermost layers and secrets the waxy layer called cuticle
regulates the water inside and outside of the cell
complex conducting tissue formed of one or more cell type
consist of
pholem

palisade
located at the top of the leaf just under epidermis where most of photosynthesis occurs
allows plant to move and bend in wind which itself helps move gases around cells
