Detailed explanation-1: -Bryophytes have no roots, leaves or stems. Mosses, hornworts, and liverworts belong to this group.

Detailed explanation-2: -In Bryophyta, organs are referred to as “Leaf like’ and ‘Stem like’ and not the true leaf and stem, because leaf and stem have the complex tissues, which perform the water and food conduction. Bryophytes being the lower plants do not have true leaf, stem and roots. They do not have vascular tissue system.

Detailed explanation-3: -The bryophytes are more differentiated than that of algae. It is thallus like and maybe prostrate or erect. They lack true roots, stems, or leaves but possess root-like, leaf-like, or stem-like structures. The plant body is attached to the substratum by root-like structures called rhizoids.

Detailed explanation-4: -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.

Detailed explanation-5: -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).
