I would like to know more about the movement structures. How do
aquatic plants move the gas in their lacunae? I thought that gasses
got around in a submerged plant's air systems just by diffusion. I
did read an article by Ole Pedersen about gas transport in the yellow
water lily, but the mechanism for that depended on the leaves of the
lily being exposed to air.
