Question

Why do floating plants have air spaces in their bodies?

Answer 1

Large air cavities provide buoyancy for the leaf. The large intercellular spaces continue into the stem and root and they provide the necessary oxygen to these organs. Leaves floating on a water surface are exposed to the sun and therefore often show a thick cuticle to avoid radiation damage.
