In which of the following groups of plants, the gametophytic phase is not dominant, photosynthetic, independent and sexually reproducing.
1 Funaria
2 Marchantia
3 Lycopodium
4 1 and 2 both
Explanation:
Lycopodium is a pteridophyte. In this group of plants, sporophyte is the dominant, photosynthetic and independent plant body.

Sporophyte, dominant, photosynthetic and independent phase of plant represents
1 Haplontic
2 Diplontic
3 Diplohaplontic life cycle
4 Both (1) and (3)
Explanation:
The case wherein the diploid sporophyte is the dominant, photosynthetic, independent phase of the plant and the gametophytic phase is represented by the single to few-celled haploid gametophyte is termed as diplontic life cycle.
