Figure 1.

Floating aquatic plants have stomata with an altered pattern of cellulose crystallinity. Crystallinity patterns in the land plant Cyclamen persicum (A,B); and aquatic plant Nuphar lutea (D,E) shown by liquid crystal polarized light microscopy (LC-PolScope). A schematic representation of the regular crystallinity pattern in angiosperm kidney-shaped stomata (C) and the altered pattern in the stomata of floating plants (F). The retardance color scale bar codes the retardance range. Scale: 25 µm.
