_______ form gametophyte in bryophytes.
1 Zygote
2 Sporophyte
3 Gametes
4 Spores
Explanation:
Spores produced by sporophyte germinate to form gametophyte
BIOXI03: PLANT KINGDOM

The main plant body of bryophyte is
1 Triploid
2 Diploid
3 Haploid
4 All of these
Explanation:
The main plant body of the bryophyte is haploid. It produces gametes, hence is called a gametophyte.

Assertion : Bryophytes possess archegonium as a female sex organ. Reason : Algae also possess the archegonium.
1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.

The plant body is thalloid in
1 Sphagnum
2 Salvinia
3 Marchantia
4 Funaria
Explanation:
Marchantia belongs to hepaticopsida. These are bryophytes in which the thallus is dorsiventrally flattened and closely appressed to the substrate.
