5 differences between Bryophyta and Pteridophyta

2
Bryophta Plant body is either leafy or thalloid.The cells in plant body are haploid.Vascular tissue like xylem and phloem absent.In life cycle the gametophyte is dominant. Sporophytic phase completely depends upon gametophyte. Pteridophyta Plant body is differentiated into root, stem and leaves.The cells in plant body are diploid.Vascular tissue like xylem and phloem present. In life cycle the sporophyte is dominant.. Sporophytic phase is independent and autotrophic

Bryophyta:

1. The main plant body is a gametophyte and haploid.
2. True roots and leaves are absent.
3. Vascular tissue is absent.
4. Archegonia with long neck having 6 vertical rows of cells.
5. Sporophyte is capsular and totally dependant on gametophyte.

Pteridophyta:

1. Main plant body is a sporophyte and diploid.
2. True roots and leaves are present.
3. Vascular tissue is present.
4. Archegonia with short neck having 4 vertical rows of cells.
5. Sporophyte is differentiated to root, stem and leaves and is initially dependent on gametophyte.

Phylum Bryophyta
1. It is mainly found in shady and damp place.
2. There is no true vascular system
3. An embryo is formed upon fertilisation.
4. The sex organs are multicellular
5.They don't have real roots, leaves and they also don't have a flower.

Phylum Pteridophyta
1.They are also found in shady and damp places.
2. It has a true vascular system.
3. Fertilised egg develop into embryo.
4. Sex organs are multicellular.
5. The body form is made up of roots, stems and leaves. They don't produce flowers.
