An inner layer, the intine, and an outer layer, the exine, are the other components of the grain wall. Web in coniferous plants, pollen is formed in the microsporangia of the male cone, whereas it is produced in the anthers of flowering plants (also termed angiosperms). Web pollination occurs when pollen grains move from anthers to a reproductively mature stigma. Web there are three parts to pollen grains. The source of nuclei for fertilisation is in the middle cytoplasmic portion. After pollen lands on the stigma, it initiates pollen tube formation. Pollen tubes are channels which grow down the length. In gymnosperms, it is formed in the microsporophylls of the microstrobili (male pollen cones ). Each microsporocyte is diploid and forms. Web in angiosperms, pollen is produced by the anthers of the stamens in flowers.
