Pteridophyta
Bryophyta
Gymnosperms
Angiosperms
The sporophyte of a bryophyte is dependent on the gametophyte. Which specific tissue within the sporophyte facilitates nutrient transfer from the gametophyte?
Seta
Capsule

a
b
c
d
Which of these features is NOT characteristic of Sphagnum?
Hygroscopic nature
Presence of elaters
Formation of peat
Absence of rhizoids
The 'protonema' stage in the life cycle of a moss is crucial for:
Sporophyte development
Spore dispersal
Water absorption
Gametophyte development
Unlike other bryophytes, Anthoceros exhibits:

Dependent gametophyte
In the life cycle of a moss, the sporophyte is:
Independent and photosynthetic.
Dependent on the gametophyte for nutrition.
The dominant phase.
Responsible for producing gametes.
