Most of the gymnosperms depend on wind for pollination. These cookies will be stored in your browser only with your consent. This means that the movement of pollen (male gamete) to ovule (female gamete) in seed plants relies on airborne transport, not water transport. Dis is beacause of the fact that the male sperms hv some sort of whip like flagella and can reach female ovules only by swimming in presence of water.
