(a) Potato starch granules in a 100 µm-diameter borosilicate capillary filled with water. (b) Optical micrograph of a 12 µm-thick laser-cut section from the centre of a dry potato starch granule attached to a glass support by beeswax; (c) Phajus grandifolius granule in a glass capillary saturated with water vapour. A water drop has condensed on the granule. (d) Polarized-light optical micrograph of a Canna edulis granule showing the location of the growth centre. |
