Question

Difference between bryophytes and pteridophytes 1

Answer 1

$brophytes$
✴️ The dominant phase is a gametophyte.

✴️ The plant body is thalloid.

✴️ vascular tissues are absent.

✴️ Sporophyte is dependent on gametophyte.

$pteridophytes$
✴️ The dominant phase is a sporophyte.

✴️ The plant body has true roots, stem and leaves.

✴️ Vascular tissues are present.

✴️ Sporophyte has independent existence.

Answer 2

Answer:

Bryophytes :

• The plant body is a gametophyte.
• The vascular tissues are absent.
• Sporophyte is parasitic over gametophyte.
• True stems and leaves are absent.
• Rhizoids are found instead of roots.
• Gametophytic phase is longer than sporophytic phase.
• Antheridium is stalked.
• Archegonium is exposed.

Pteridophytes :

• The plant body is a sporophyte.
• The vascular tissues are present.
• Gametophyte and sporophyte are independent.
• Body is differentiated into roots, leaves and stem.
• Plants possess true stem and leaves.
• Sporophytic phase is longer than gametophytic phase.
• Antheridium is sessile.
• Archegonium is partially embedded.
