'''Leaves''' have many tissues inside them found in layers:
*Upper Epidermis - A layer of cells at the top of the leaf that make a [[Waxy Cuticle|waxy cuticle]] on top to keep the [[leaf]] [[waterproof]].
*[[Palisade Tissue]] - A layer of [[Palisade Cell|palisade cells]] which have lots of chloroplasts in them for [[photosynthesis]].
*[[Spongy Mesophyll Tissue]] - A layer of [[Spongy Mesophyll Cell|spongy mesophyll cells]] that have irregular shapes to allow [[air]] to pass through the [[leaf]].
