This Video contains Multiple choice questions about Bryophytes mcqs . Bryophytes are important topic of plant kingdom mcqs.They are an informal group consisting of three divisions of non-vascular land plants (embryophytes): the liverworts, hornworts and mosses. They are characteristically limited in size and prefer moist habitats although they can survive in drier environments. The bryophytes consist of about 20,000 plant species. • General Characteristics of Bryophytes: • a) Plants occur in damp and shaded areas • The plant body is thallus like, i.e. prostrate or erect • b) It is attached to the substratum by rhizoids, which are unicellular or multicellular • c) They lack true vegetative structure and have a root-like, stem-like and leaf-like structure • d) Plants lack the vascular system (xylem, phloem) • e) Bryophytes show alternation of generation between independent gametophyte with sex organs, which produces sperm and eggs and dependent sporophyte which contains spores • f) The dominant part of the plant body is gametophyte which is haploid • g) The thalloid gametophyte is differentiated into rhizoids, axis and leaves • h) The gametophyte bears multicellular sex organs and is photosynthetic • The antheridium produces antherozoids, which are biflagellated • I) The shape of an archegonium is like a flask and produces one egg • j) The antherozoids fuse with egg to form a zygote • k) The zygote develops into a multicellular sporophyte • The sporophyte is semi-parasitic and dependent on the gametophyte for its nutrition • l) Cells of sporophyte undergo meiosis to form haploid gametes which form a gametophyte • m) The juvenile gametophyte is known as protonema • n) The sporophyte is differentiated into foot, seta and capsule • #PlantKingdom • #Bryophytes • #MCQs
