===About Photosynthesis===
: [[Photosynthesis]] takes place in the [[chloroplast]].
: [[Chlorophyll]] is a [[catalyst]] for [[photosynthesis]].
: Without [[chlorophyll]], [[photosynthesis]] cannot happen.
 
===Adaptations for Photosynthesis===
: [[Plant]]s have evolved an [[organ]] called a [[leaf]] which is specially adapted for [[photosynthesis]].
: [[Leaf|Leaves]] are thin and wide to create a large [[Surface Area|surface area]] to collect [[light]].

: The [[leaf]] has [[Xylem]] vessels to supply [[water]] collected by the [[root]]s.
: The [[leaf]] has air gaps to allow [[Carbon Dioxide|carbon dioxide]] and [[oxygen]] to flow through the [[leaf]].
: The [[leaf]] has a layer of [[Palisade Cell|palisade cells]] which have lots of [[chloroplast]]s inside for [[photosynthesis]].
: The [[leaf]] has [[Guard Cell|guard cells]] and [[Stoma|stomata]] which can open and close. This way if the [[leaf]] gets [[dehydrate]]d the [[stoma|stomata]] will close and stop [[Carbon Dioxide|carbon dioxide]] getting in, stopping [[photosynthesis]].
