Epidermis
Must be reasonably waterproof: consists of guard cells and trichomes
Initiation and development of leaves
Basal angiosperm and Eudicots
Leaf primordium
Outward protrusion of cells at the base of meristem
Monocots
Initiated by the expansion of some shoot apical meristem cells to form a leaf primordium
