The angiosperm life cycle, in many ways, follows the basic life cycle pattern for land plants (embryophytes), with modifications characteristic of the seed plant … WebThe pollen grains carry the male gametes of the plant. The small haploid (1 n) cells are encased in a protective coat that prevents desiccation (drying out) and mechanical damage. Pollen can travel far from the sporophyte that bore it, spreading the plant’s genes and avoiding competition with other plants.
