Solution
Answer: (a) and (b) Gametophytes of bryophytes and seedless vascular plants.
Gametophytes produces gametes in separate multicellular structures. The structure that produces eggs is called an archegonium while the structure that produces sperm is called an antheridium.
Antheridia are present in the gametophyte phase of cryptogams like bryophytes and ferns.
Seedless vascular plants can reproduce sexually only when a film of water covers the gametophyte. Eggs form in archegonia, and sperm form in antheridia. The archegonia and antheridia develop on the lower surfaces of the gametophytes.
