As we know NEET demands the attention of students in understanding Cell at the Molecular Level and concrete basic understanding but once done it only gets easier from there. Mastering the Below MCQ on Bryophytes should boost your NEET entrance exam Preparation.

Bryophytes or  Amphibians of Plants collectively name for the mosses, liverworts and hornworts that are found commonly growing in moist shaded areas in the hills. Bryophytes are also called amphibians of the plant kingdom because these plants can live in soil but are dependent on water for sexual reproduction. They are generally occurring in Moist, humid and shaded localities. They occur most abundantly in relatively unpolluted areas. Bryophytes don’t have true roots. All bryophytes play a key role in plant succession on bare rocks / soil.

The detailed Study of Bryophytes is known as Bryology. Liverwort (Cryptothallus) which lacks chlorophyll and relies on a fungal partner for food. They are spore-producing, rather than seed-producing, plants and they are all without flowers. Bryophytes vary in size from plants to plants only slightly over a millimeter tall to trailing species which grow to strands well over a meter long.

They have root-like anchoring structures, called rhizoids, but these (unlike the roots of most plants) do not actively extract minerals and water from the substrate. The life cycle of bryophytes shows two distinct phases sucb as a haploid gametophytic phase and a diploid sporophytic phase alternating with each other The adult plant body represents the gametophyte. A short-lived sporophyte occurs as a parasite on the gametophyte. It is the adult plant body in bryophytes. It is either thalloid or in the form of a leaty shoot with stem-like and leaf-like structures, Roots are absent and instead unicellular or multicellular thread-like rhizoids are present.
