Hi,
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.
Pteridophytes:-it include horstell and ferns. These are used for medicinal purposes and as soil-binders. These are found in cool,damp and shady places.these are also frequently growth.they are the 1st terrestrial posses vascular tissue. the main plant body is sporophytic. I.e (a) Selaginella (b) Equisetum (c) Ferns (d) Salvinia
BRYOPHYTES:- it include the various mosses and liveworts that are found in commonky growing in moist shaded areas in the hills.These are also called as amphibians of the plant kingdom because these plants can live in soil but are dependent on water for sexual reproduction. They usually occur in damp,humid and shaded. They play an important role in plant succession on bare rocks/soil.it produce gametes,hence it is called as gametophyte.thy may possess root-like,leaf-like or stem-like str.the main plant body of the brynphyte is heploid. I.e (a)Liveworts (mosses).
I hope you understood it.

In Bryophyta, the body is differentiated into stem and leaf only. They also do not have vascular tissues. Bryophytes are also called 'amphibians' of the plant kingdom. Some examples are moss and marchantia.
In Pteridophyta, the body is differentiated into stem, leaves as well as root. They also have a large vascular bundle. Some examples are ferns and marsilea.

- bryophtyes have a gametophytic plant body while pteridophtes have a saprophytic.
- Bryophytes is either thallose or folliose but true stem and leaves are always absent whereas pteridophytes possess true stem and leaves.
- in bryophytes, fixation of plant body is carried out by rhizoids but in pteridophytes, it is done by roots.
- bryophtes are non vascular in nature whereas pteridophytes are vascular.
