I say naively, because after a little background reading, apparently this isn't the ideal way to study pollen properly! Pollen grains have an oil film that can make the study of fine detail more difficult and procedures for removing this by an alcohol wash are described in the references below.

Pollination, the process by which pollen grains transfer their male nuclei (gametes) to the ovary of a flower. The pollen grains land on the stigma and form a pollen tube that grows down into the ovary. The male nuclei travel along the pollen tube.

Measurements of δ13C, δ15N and C : N ratios on modern pollen grains from temperate plants, including whole grains as well as extracted sporopollenin, were analysed in order to characterize physiological plant types at the pollen level and to determine the variation of these parameters in modern pollen grains of the...
