EVERYDAY SCIENCE

Detailed explanation-1: -Ferns, club mosses, horsetails, and whisk ferns are seedless vascular plants that reproduce with spores and are found in moist environments.

Detailed explanation-2: -Higher plants such as trees reproduce by seeds while lower plants such as mosses and ferns reproduce by spores.

Detailed explanation-3: -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-4: -Primitive seedless plants, like ferns, mosses and liverworts, reproduce with spores. Spores, like seeds, are ultimately the result of sexual reproduction. Unlike seeds, spores are usually a single reproductive cell.

Detailed explanation-5: -Ferns generally reproduce by producing spores. Similar to flowering plants, ferns have roots, stems and leaves. However, unlike flowering plants, ferns do not have flowers or seeds; instead, they usually reproduce sexually by tiny spores or sometimes can reproduce vegetatively, as exemplified by the walking fern.
