●Due to the alteration in the gametophytic and sporophytic life cycle Bryophyte shows haplo -diplontic  both types of life cycle. 

●Major part is dominated by the haploid gametophytic phase. 

●Independent, photosynthetic and haploid phase.

● The antheridium and archegonia are formed inside the gametophyte.

● Later fertilization will occur and zygote will be formed. 

●Zygote develops into sporophytes which are small & are dependent on the gametophyte for water and food.
