  • Adaption of Leaves for Gas Exchange
    • Leaves are broad so large SA
    • Thin so gases only have to travel a short distance
    • Air spaces letting gases move easily between cells
    • Stomata allow gases to diffuse in and out and let water out - transpiration
    • Stomata close when dark or water from roots dry up- no photosynthesis, leaf does not dry out
    • Opening and Closing of Stomata controlled by the guard cells
