The Juvenile stage in Mosses is called as
1 Gametophore
2 Protonema
3 Gemma

Explanation:
In case of Mosses the spores attain a green filamentous and branched structure called protonema that represents a juvenile stage of moss gametes. The moss lifecycle is completed in two distinct stages -the gametophyte and the sporophyte. The term that describes this type of life history is called alternation of heteromorphic generations.

Plants like Marchantia and Funaria produce gametes by mitosis, because
1 Plant body is haploid
2 Gametophyte is diploid
3 They are gametophytes
4 They are dioecious
Explanation:
In Marchantia and Funaria plant body is haploid and posses tiny leaf like appendages. The leafy stage bears sex organs. They have vegetative reproduction takes place by fragmentation and budding in secondary protonema.
