Detailed explanation-1: -Nonvascular plants are bryophytes. Despite the dominance of vascular plants today, more than 17, 000 species of bryophytes still survive. They include liverworts, hornworts, and mosses.

Detailed explanation-2: -Mosses, and their relatives the hornworts and liverworts are regarded as the first true plants on dry land. These groups, collectively known as the bryophytes, are small and inconspicuous, damp-loving plants.

Detailed explanation-3: -Mosses are non-flowering plants which produce spores and have stems and leaves, but don’t have true roots. Mosses, and their cousins liverworts and hornworts, are classified as Bryophyta (bryophytes) in the plant kingdom.

Detailed explanation-4: -What are bryophytes? Bryophytes is the informal group name for mosses, liverworts and hornworts. They are non-vascular plants, which means they have no roots or vascular tissue, but instead absorb water and nutrients from the air through their surface (e.g., their leaves).

Detailed explanation-5: -Bryophyta is a group of plants which do not bear fruits, seeds and vascular tissues. They are known as ‘amphibians of plant kingdom’. Their body is thalloid and green due to the presence of chloroplast. Male sexual organ is antheridium and female sexual organ is archegonium.
