Detailed explanation-1: -In seedless vascular plants, such as ferns and horsetails, the plants reproduce using haploid, unicellular spores instead of seeds. The spores are very lightweight (unlike many seeds), which allows for their easy dispersion in the wind and for the plants to spread to new habitats.
Detailed explanation-2: -Vascular plants like ferns and horsetails don’t have seeds, they reproduce with spores! These plants have two stages, the gametophyte stage and the sporophyte stage. The sporophyte stage is what you are probably most familiar with. This is when the fern has fronds with spores on the underside.
Detailed explanation-3: -In seedless vascular plants such as ferns, the sporophyte releases spores from the undersides of leaves. The spores develop into tiny, separate gametophytes, from which the next generation of sporophyte plants grows.
Detailed explanation-4: -Sporangia in Seedless Plants The sporophyte bears the sporangia (singular, sporangium): organs that first appeared in the land plants. The term “sporangia” literally means “spore in a vessel”: it is a reproductive sac that contains spores.
Detailed explanation-5: -Numerous seedless plants reproduce asexually through the vegetative, budding, cutting, fragmentation, layering, and micropropagation methods.
