Detailed explanation-1: -Pteridophytes differ from bryophytes in having well-differentiated body structures such as roots, stems, and leaves. They do not have vascular structures within the body. They have well-developed vascular tissues to supply water and minerals to body parts. They have primitive rhizoid structures to anchor to the ground.

Detailed explanation-2: -Pteridophytes are tracheophyte vascular plants i.e. they have tissues specialized in conduction of water and nutrients. Bryophytes are nonvascular plants. In pteridophytes therefore the substance transport is done through vessels and in bryophytes that transport occurs by diffusion.

Detailed explanation-3: -Primary characteristics of Pteridophytes are as follows: They are seedless, vascular plants that show true alternation of generations. Furthermore, the sporophyte has true roots, stems and leaves. They reproduce by spores, which are developed in sporangia. They may be homosporous or heterosporous.

Detailed explanation-4: -The most advanced sporophyte, due to the presence of intercalary meristem, is found in Anthoceros (a hornwort).
