• Bryophyte shows haplodiplontic life cycle due to alternation between gametophytic and sporophytic phase of life.

• In bryophytes major part of the life cycle is dominated by haploid gametophytic phase.

• Gametophyte is independent, photosynthetic and haploid phase.

• Antheridium and archegonia are formed in gametophyte.

• Fertilization occurs, zygote is formed.

• Zygote developed into sporophytes which is small & is dependent on gametophyte for water and food.
