How many of the above statement are correct?
When and where does reduction division take place in the life cycle of a liverwort, a moss, a fern, a gymnosperm and an angiosperm?
Differentiate between the following:
$(i)$ red algae and brown algae
$(ii)$ liverworts and moss

$(c)$ Funaria | $(iii)$ Dominant diploid sporophyte alternating with reduced gametophyte called prothallus |
$(d)$ Cycas | $(iv)$ Dominant haploid leafy gametophyte alternating with partially dependent |
