Detailed explanation-1: -Pteridophytes are seedless plants whereas, phanerogams are seed bearing plants. 4. Pteridophytes can reproduce by formation of spores whereas, phanerogams cannot reproduce by formation of spores.

Detailed explanation-2: -Seedless vascular plants are plants that contain vascular tissue, but do not produce flowers or seeds. In seedless vascular plants, such as ferns and horsetails, the plants reproduce using haploid, unicellular spores instead of seeds.

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: -Ferns are seedless, vascular plants. They contain two types of vascular tissue that are needed to move substances throughout the plant. Evolutionarily, this addition of vascular tissue to plants is what allowed ferns to grow up and out rather than just spreading along the ground.
