Question

Among the following which is not characteristic feature of bryophyta [DPMT 1983]
A) Motile sperms
B) Presence of archegonium
C) Water essential for fertilization
D) Photosynthetically independent sporophyte

Answer 1

The correct option is, (D) Photosynthetically independent sporophyte.

• Bryophyte's sporophyte has a photosynthetic plastid. It cannot live apart from the gametophyte. The sporophytes of a bryophyte stay attached to its main body gametophyte throughout the life of the sporophyte and are dependent on the gametophyte.

What is bryophyta?

• Bryophytes is a proposed taxonomic class that includes the liverworts, hornworts, and mosses, which are non-vascular terrestrial plants (embryophytes).

• They are typically small and prefer damp surroundings, though they can thrive in drier ones as well.

• There are over 20,000 plant species in the bryophytes.

• Bryophytes have enclosed reproductive organs (gametangia and sporangia), but no flowers or seeds. They reproduce sexually by spores and asexually through fragmentation or gemma formation.

• Though bryophytes were once thought to be a paraphyletic group, practically all current phylogenetic evidence now confirms the monophyly of this category, as defined by Wilhelm Schimper in 1879.

• Bryophyte is derived from the Ancient Greek words v (bron) 'tree moss, liverwort,' and (phutón) 'plant.'

Hence, The sporophyte of a bryophyte contains a photosynthetic plastid. It can't exist without the gametophyte. The sporophytes of a bryophyte remain linked to their main body gametophyte throughout their lives and are completely reliant on it.
