WebThis process is similar to production of gametes in animals (note that haploid gametes in plants are produced by mitosis from a haploid gametophyte). Upon maturity, the microsporangia burst, releasing the pollen grains from the anther where they have the opportunity to be transported to stigmas by wind, water, or an animal pollinator.
