Bryophytes include the various mosses and liverworts 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.
Bryophytes in general are of little economic importance but some
mosses provide food for herbaceous mammals, birds and other animals.
The
main plant body of the bryophyte is haploid. It produces gametes, hence
is called a gametophyte.
The male sex organ is called antheridium. They produce biflagellate
antherozoids. The female sex organ called archegonium is flask-shaped
and produces a single egg.
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.
