Pollination

Pollination comes about when the haploid pollen combines with the haploid gametes of the female flower (gynoecium) to form a new diploid seed. Wind and insects pollinate some plants, while others are self-pollinating. Self-pollinated vegetables include tomatoes, beans, peas, and corn, which makes it extremely easy to save seed from them, because they tend to come out true and they are not easily cross-pollinated.
