Detailed explanation-1: -The ferns, gymnosperms, and flowering plants are all vascular plants. Because they possess vascular tissues, these plants have true stems, leaves, and roots.

Detailed explanation-2: -The correct answer is ‘angiosperms’.

Detailed explanation-3: -Ferns & Fern Allies Like forbs, grasses and trees, ferns are “vascular” plants. They have special tissues that transport fluids and nutrients internally. They also have true root systems, leaves and stems. However, ferns are unlike most plants because they do not produce flowers and seeds.

Detailed explanation-4: -Pteridophytes has proper vasculature, which means xylem and phloem is present. Plants do not have roots, instead, rhizoids are present and help in anchoring. Roots are present in these plants. It does not have any true stems or leaves.

Detailed explanation-5: -All land plants except Bryophytes (mosses, liverworts, and hornworts) have true roots. Bryophytes have root-like structures called rhizoids that anchor them to their substrate but are not involved in water absorption (which is less important for Bryophytes because they can only survive in very moist environments).
