HORTICULTURE

Detailed explanation-1: -Seedless vascular plants reproduce through unicellular, haploid spores instead of seeds; the lightweight spores allow for easy dispersion in the wind. Seedless vascular plants require water for sperm motility during reproduction and, thus, are often found in moist environments.

Detailed explanation-2: -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-3: -Ferns, club mosses, horsetails, and whisk ferns are seedless vascular plants that reproduce with spores and are found in moist environments.

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: -How do nonvascular plants and seedless vascular plants reproduce? Nonvascular plants and seedless vascular plants both reproduce by sexual means in which there is the production of male and female gametes, and asexual means in which there is a production of spores by the sporophytes.
