In MOSSES (a bryophyte), the predominant gametophyte has TWO stages — identify them in correct sequence.
ALeafy stage → Protonema
BAntheridium → Archegonium
CProtonema (filamentous, develops from spore) → LEAFY stage (upright slender axes with spiral leaves, bears sex organs)
DFoot → Seta → Capsule
Answer & Solution
Correct answer: C. Protonema (filamentous, develops from spore) → LEAFY stage (upright slender axes with spiral leaves, bears sex organs)
Moss gametophyte stages: (1) Protonema — creeping green filamentous stage from spore; (2) Leafy stage — upright with spiral leaves, bears antheridia and archegonia at apex. Foot/Seta/Capsule are the sporophyte's structures.
