===About Leaves===
: The [[Cell (Biology)|cells]] in '''leaves''' have many [[chloroplast]]s inside them.
: '''Leaves''' produce food that is sent to the [[root]]s through the [[phloem]] which is part of a [[Plant Vein|plant vein]] that carries sap.
'''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 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]].
*Lower Epidermis - A layer of [[Cell (Biology)|cells]] at the bottom of the [[leaf]] with [[Stoma|stomata]] to allow [[air]] into and out of the [[leaf]].
