| Video Discription | 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 zF0XQiqNoW0 |
