Which plant group is called the amphibians of the plant kingdom ?

Bryophyta

The correct answer is Option (3) – Bryophyta

Bryophytes are called amphibians of the plant kingdom because these plants need both water and soil for their survival.The plant body is commonly differentiated to form stem and leaf-like structures. However, there is no specialised tissue for the conduction of water and other substances from one part of the plant body to another. Examples are moss (Funaria) and Marchantia.
