Scanning Electron Microscopy was used to analyze the surface changes taking place in the starch granules of lentil cotyledons during germination. In the initial germination phases, the granules exhibited a smooth surface and their interior was compact. As time progressed, the deposition of membrane‐like material onto surface of the granules was seen to increase, and at 10 days their interior could be described as compartmentalized. After this it was possible to observe starch fragments with polyaedral shapes; these are thought to have originated in the interior of the granules and to have dispersed throughout the cell during their endogenous degradation.
