Why are bryophytes called the amphibians

They inhabit two well-defined habitats i.e. land and water.

(b) Bryophytes can complete their life cycle without water; water is required for fertilisation,

(c) Water also plays an important role in dehiscence of antheridium and archegonium.

(d) As it lacks proper vasculature, water conduction occurs through capillary action.

Hence a thin film of water is required on land, for survival
