Question

difference between pryphyto and terophyto​

Answer 1

Liverworts, hornworts, and mosses are the examples of bryophytes. These are non-vascular plants i.e. do not contain xylem and phloem tissues. Spikemosses, clubmosses, ferns, quillworts are the examples of pteridophytes. They are termed as vascular plants as they contain xylem and phloem tissues.

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.
