Pteridophytes include those plants that lack flowers and do not produce seeds. Their body is well differentiated into roots, stems and leaves. They have a well-developed vascular system with multicellular sex organs.

Examples of Pteridophytes- Selaginella, Dryopteris, Pteris, etc.

Bryophyta:

1. Plant body is gametophytic.

2. Plant body is either thallose and/or folliose. However, real stem and leaves are always absent. 

3. Fixation of plant body is carried out by rhizoids.

4. Sporophyte is parasitic over the gametophytic plant body throughout its life.

5. Bryophytes are non-vascular in nature.

Pteridophyta:

1. Plant body is sporophytic.

2. Real stem and leaves are present.

3. Fixation of plant body is carried out by roots.

4. The gametophyte is small and independent.

5. Pteriodophytes are vascular plants.
