WebFerns and horsetails have two free-living generations: a diploid sporophyte generation (spore-producing plant) and a haploid gametophyte generation (gamete-producing plant). Plants we see as ferns or horsetails are the sporophyte generation. The sporophyte generally releases spores in the summer. WebFinal answer. Step 1/3.

In seed plants, the evolutionary trend led to a dominant sporophyte generation, and at the same time, a systematic reduction in the size of the gametophyte: from a conspicuous structure to a microscopic cluster of cells enclosed in the tissues of …

WebThe haploid multicellular plants (or algae) are called gametophytes, because they make gametes using specialized cells. Meiosis is not directly involved in making the gametes in this case, because the organism is already a haploid. Fertilization between the haploid gametes forms a diploid zygote.
WebThe alternation of generations is an important concept in the evolution of plants. All land plants have alternation of generations.
