Why are bryophytes called the amphibians of the plant kingdom?

(N/A) Bryophytes are known as the amphibians of the plant kingdom because they can live in soil but are dependent on water for sexual reproduction.
$1$. These plants typically grow in moist,shaded,and damp areas.
$2$. The male gametes,known as antherozoids,are flagellated and motile.
$3$. They require an external film of water to swim from the male sex organ (antheridium) to the female sex organ (archegonium) to achieve fertilization.
$4$. Since they require both land for survival and water for the completion of their life cycle,they are termed amphibians of the plant kingdom.
