Describe the male gametophyte of a seed plant

WebMale gametes are pollen grains which are found inside the anther, whereas female gamete is an egg produced inside the ovule. What is the difference between male gametophyte and a microspore? A microspore is produced from the diploid sporophytic body after meiosis and the male gametophyte is produced from those microspores. WebThe short, blue-green gametophyte is the dominant phase of the lifecycle of a hornwort. The narrow, pipe-like sporophyte is the defining characteristic of the group. The sporophytes emerge from the parent gametophyte and continue to grow throughout the life of the plant (Figure 4). Stomata appear in the hornworts and are abundant on the sporophyte.

WebThe male gametophyte of flowering plants produces haploid male gametes. Conclusion A gametophyte is the multicellular haploid phase of every plant and algae’s life cycle. Archegonium and antheridium are two forms of gametophytes found in lower plants that produce eggs and sperms, respectively. WebThe trend toward a dominant sporophyte stage is now complete. The gametophytes of seed plants are microscopic. The female gametophyte consists of a handful of cells buried in the tissues of the sporophyte. The male gametophyte, the pollen grain, has a brief free-living stage while it is carried from plant to plant by wind, water, or animals.
