SEM images of the seagrass CaCO3 deposits: (a) Paradermal-horizontal view of the external (Ext) and internal (Int) sides of the leaf cuticle; (b) close-up of the internal side; (c,d) transversal-vertical views of the leaf showing the single epidermal layer (Ep) and the CaCO3 deposits between the cells; (e,f) close-ups of the epidermal cell wall showing the abundant presence of aragonite crystals; and (g,h) view of the CaCO3 deposits on the aerenquima cell walls (Aq).
