Detailed explanation-1: -For these plants, the name says it all. Seedless vascular plants have vascular tissue but do not have seeds. Remember that vascular tissue is specialized tissue that transports water and nutrients throughout the plant.

Detailed explanation-2: -Ferns are considered the most advanced seedless vascular plants and display characteristics commonly observed in seed plants. Ferns form large leaves and branching roots. In contrast, whisk ferns, the psilophytes, lack both roots and leaves, which were probably lost by evolutionary reduction.

Detailed explanation-3: -The seedless vascular plants include club mosses, which are the most primitive; whisk ferns, which lost leaves and roots by reductive evolution; and horsetails and ferns. Ferns are the most advanced group of seedless vascular plants.

Detailed explanation-4: -they both use chlorophyll a, chlorophyll b, and carotenoid pigments during photosynthesis. the primary food reserve of both is starch. they both have cellulose cell walls.
