Detailed explanation-1: -Examples of seedless vascular plants include ferns, clubmosses, whisk ferns, and horsetails.

Detailed explanation-2: -Modern-day seedless vascular plants include club mosses, horsetails, ferns, and whisk ferns.

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: -The vascular plants, or tracheophytes, are the dominant and most conspicuous group of land plants. They contain tissue that transports water and other substances throughout the plant. More than 260, 000 species of tracheophytes represent more than 90 percent of the earth’s vegetation.

Detailed explanation-5: -Lycophytes and pterophytes are referred to as seedless vascular plants, because they do not produce seeds. The seed plants, or spermatophytes, form the largest group of all existing plants, and hence dominate the landscape.
