It’s main functions are photosynthesis(which means organisms and green plants absorbs sunlight and turn them into nutrients) and gas exchange.A leaf is often flat(but not always) so it absorbs the most light ,and thin,so that the sunlight can get to the chloroplasts(which means green plant cells containing chlorophyll and that chlorophyll makes plants green) in the cells.Most leaves have stomata,which open and close.They collect carbon dioxide ,oxygen and water vapour and exchange with the atmosphere.

Leaves go all golden and crispy in the Autumn(which contains September,October,November).In the winter all of the leaves die of.Winter,which is a cold time of year,contains December,January,February.In the spring all of the flower and leave buds come back.Spring,which can be a humid time of year,contains March,April,May.Finally summer,which can be a very hot time of year,contain June,July,August.The leaves are back and then the life of leaves can repeat.It’s like an infinite circle( ⚪️ ).
