Sexual reproduction in liverworts takes place by
1 Gemmae formation
2 Special spores
3 Sexual reproduction is absent
4 Fusion of male and female gametes
Explanation:
During sexual reproduction, male and female sex organs are produced either on the same or on different thalli. These sex organs produce gametes, which fuse to form zygote (sporophyte).

The sporophyte in liverworts
1 Is differentiated into foot, seta and capsule
2 Produces gemma
3 Gives nutrition to the gametophyte
4 All of them

If the rhizoids of Marchantia has 10 chromosomes, the primary protonema will have
1 10 chromosomes
2 5 chromosomes
3 15 chromosomes
4 20 chromosomes
Explanation:
Rhizoids are haploid structures that are responsible for the attachment of thallus to substratum. Primary protonema is a stage of gametophyte which is haploid too. Thus, both will have same number of chromosomes.
