    Cross-pollination, also called allogamy, occurs when pollen is delivered from the stamen of one flower to the stigma of a flower on another plant of the same species.
    Snails or other insects like bees pollinate plants inadvertently! They are out to obtain nectar from plants, and on their feet or feelers or bodies, perhaps, in the case of snails, spread a plant’s (male) pollen from the stamens onto the female part (pistils) of the same type of plant they next visit in their quest for nectar.
