bryophyta और pteridophyta के बीच का अंतर
Answers
Bryophyta means it is a traditional name used to refer all embryophytes that do not have true vascular tissure and are therefore called non vascular plants.
examples-mosses,liverworts.
pteridophyta are vascular plants with xylem and phloem that reproduce and disperse via spores. Because they produce niether seeds nor flowers, they are referred to as cryptogams.
examples-horsetales, clubmosses

hey there!!
Difference # Bryophytes:
1. Plant body is gametophyte.
2. Vascular tissues are absent.
3. Sporophyte is parasitic over gametophyte.
4. Plant body can be thallose or toliose.
5. True stem and leaves are absent.
6. Roots are absent. Instead, rhizoids occur.
7. Haploid or gametophytic phase is longer lived while sporophyte phase is shorter lived.
8. Antheridium is stalked.
9. Archegonium is commonly exposed.
10. Neck of archegonium is formed of 5-6 rows of cells.
Difference # Pteridophytes:
1. Plant body is sporophyte.
2. Vascular tissues are present.
3. Both sporophyte and gametophyte are independent.
4. Plant body is differentiated into stem, leaves and roots.
5. Plants possess true stem and leaves.
6. Roots are present.
7. Diploid or sporophytic phase is longer lived while gametophytic phase is shorter lived.
8. Antheridium is sessile.
9. Archegonium is partially embedded.
10. Neck of archegonium has four rows of cells.
