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
