Answer:
General Characteristics of Bryophytes:
★ Plants occur in damp and shaded areas.
★ The plant body is thallus like, i.e. prostrate or erect.
★ It is attached to the substratum by rhizoids, which are unicellular or multicellular.
★ They have a root-like, stem-like and leaf-like structure and lack true vegetative structure.
★ Plants lack the vascular system (xylem, phloem).
★ The dominant, a part of the plant body is gametophyte which is haploid.
★ The thalloid gametophyte is divided into rhizoids, axis and leaves.
★ The gametophyte bears multicellular sex organs and photosynthetic.
★ The antheridium produces antherozoids, which are flagellated.
★ The shape of an archegonium is a sort of a flask and produces one egg.
★ The antherozoids fuse with egg to make a zygote.
★ The zygote develops into a multicellular sporophyte.
★ The sporophyte is semi-parasitic and dependent on the gametophyte for its nutrition.
★ Cells of sporophyte undergo meiosis to form haploid gametes which form a gametophyte.
★ The juvenile gametophyte is known as protonema.
★ The sporophyte is differentiated into foot seta and capsule.
