'''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]].

: '''Leaves''' contain [[Cell (Biology)|cells[[ with many [[chloroplast]]s for [[photosynthesis]].
: '''Leaves''' have [[air]] gaps between the [[Spongy Mesophyll Cell|spongy mesophyll cells]] to allow [[Gas Exchange in Plants|gas exchange]].
: '''Leaves''' usually have more [[Guard Cell|guard cells]] and [[Stoma|stomata]] on the underside (lower epidermis) than the top side (upper epidermis).
