Gametophyte is a dominant phase in the life cycle of a bryophyte. It is more conspicuous, long living, independent, green and freely branched whereas, the sporophytic phase is short lived and dependent upon the gametophyte. The main plant body is haploid and bears sex organs i.e., antheridium and archegonium. Antheridium produces a large number of flagellated male gametes called antherozoids and archegonium is flask shaped with tubular neck and swollen venter. The gametophytic plant body of bryophytes is thalloid in liverworts whereas foliose in mosses. In liverworts, the thallus is differentiated into a dorsal photosynthetic and ventral storage region. In mosses, the gametophyte has two growth stages- protonema stage and leafy stage or gametophore.
Direction : In the following questions the Assertions (A) and Reasons (R) have been put forward. Read both the statements and choose the correct option from the following :
Assertion : Moss protonema resemble green alga.
Reason : It develops unicellular sex-organs.
  • a)
    Both A and R are true, and R is the correct explanation of A.
  • b)
    Both A and R are true, but R is not the correct explanation of A.
  • c)
    A is true but R is false.
  • d)
    A is false but R is true.
Correct answer is option 'C'. Can you explain this answer?

Explanation:

Assertion : Moss protonema resemble green alga.

- Moss protonema is a filamentous green structure that resembles green algae in appearance.
- Both moss protonema and green algae have a similar morphology with elongated, branching structures.

Reason : It develops unicellular sex-organs.

- Moss protonema does not develop unicellular sex organs. Instead, it gives rise to the leafy gametophyte stage which bears sex organs called antheridia and archegonia.
- Antheridia produce flagellated male gametes called antherozoids, while archegonia have a flask-shaped structure with a tubular neck and swollen venter for fertilization.

Therefore, the assertion that moss protonema resembles green algae is true, but the reason that it develops unicellular sex organs is false. Moss protonema develops into the leafy gametophyte stage with multicellular sex organs.
