8. • After Fertilisation zygote is formed.
• Zygote Develops into Embryo
• Embryo Develops into Sporophyte.
• Completely dependent on
gametophyte.
• nutritionally
• Generally differentitated into foot,seta
and capsule
• Foot and capsule(Corsinia)
• Or only capsule (Riccia)

9. • Meispore – First cell.
• Dominant phase.
• Produces anthredia and
archegonia.
• Zygote develops sporophyte and it
remains attached to gametophyte.
• Nutritionally independent.
