The stigma is sticky so that it can pick up the pollen grains easier, or, in other words, so that the pollen wll stick to it.
Depending on the type of pollinators, the pollen grains may be sticky or light. Exine present on the pollen grains as the outermost covering layer is contributed by the tapetum cells.
