A Correct answer
Explanation

Bryophytes are known as ‘amphibians of plant kingdom’ because they can adapt to both land and water habitats. In their vegetative structure, bryophytes completely adapt to the land habitat. However, they still depend upon water for sexual reproduction because the swimming habit is retained by their sperms.
