Bryophytes are also called amphibians of the plant kingdom because these plants can live in soilbut are dependent on water for sexual reproduction. They usually occur in damp, humid and shaded localities. They play an important role in plant succession on bare rocks/soil. Tt are fould body of bryophytes is more differentiated than that of algae. main plant body of the bryophyte is haploid. It produces gametes, hence The male sex organ is antherozoids. The is called antheridium. They produce biflagellate and produces a single egg. The antherozoids are released into water where they come in contact with archegonium. An antherozoid fuses with the egg to produce the with archegonium. An antherozoid fuses with the immediately. They produce a multicellular body called a sporophyte. The sporophyte is not free-living but attached to the photosynthetic gametophyte and derives nourishment from it. Some cells of the sporophyte undergo reduction division (meiosis) to produce haploid. spores. These spores germinate to produce gametophyte. Bryophytes in general are of little economic importance but some mosses provide food for herbaceous mammals, birds and other animals. .) "Species of Sphagnum, a moss, provide peat that have long been used as fuel, and as packing material for trans-shipment of living material because of their capacity to hold water. Mosses along with lichens are the first organisms to colonise rocks and hence, are of great ecological importance. They decompose rocks making the substrate suitable for the growth of higher plants. Since mosses form dense mats on the soil, they reduce the impact of falling rain and prevent soil erosion. The bryophytes are divided into liverworts and mosses. 3.2.1 Liverwortsatia, Micia funaria, towachden Polyt The liverworts grow usually in moist, shady habitats such as banks of sphoghe streams, marshy ground, damp soil, bark of trees and deep in the woods. The plant body of a liverwort thalloid, ).g. (Marchantia) The thallus is dorsiventral and closely appressed to the substrate. The leafy members have tiny leaf-like appendages in two rows on the stem-like structures. Asexual reproduction in liverworts takes place by fragmentation of thallii, or by the formation of specialised structures called gemmae (sing. gemma). Gemmae are green, multicellular, asexual buds, which develop in small receptacles called gemma cupsNocated on the thalli. The gemmae become detached from the parent body and germinate to form new individuals. During sexual reproduction, male and female sex
