NEET BIOLOGY

Detailed explanation-1: -The correct option is (a). Bryophytes are a category of nonvascular plants that include the liverworts, hornworts, and mosses. In the case of all of these organisms, the gametophyte generation is dominant, meaning that this generation is larger and more noticeable than the sporophyte generation.

Detailed explanation-2: -The plant body of bryophytes is more differentiated than that of algae. It is thallus-like and prostrate or erect and attached to the substratum by unicellular or multicellular rhizoids which are root-like structures. They lack true roots, stem or leaves.

Detailed explanation-3: -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-4: -Which of the following statements is true of the bryophyte gametophyte generation? It is photosynthetically independent. An ovule can be defined as: a sporangium protected by sporophyte tissue layers and containing a single non-dispersed spore that has developed into a female gametophyte.

Detailed explanation-5: -Complete answer: > Bryophytes-The Main plant body of bryophytes is haploid and is an independent gametophyte. This gametophyte gives rise to diploid sporophyte.
