WebSporophyte: The spore-producing phase of a plant’s life cycle is known as sporophyte. Plants reproduce in two stages: sexual and asexual reproduction. The alternation of generation separates these two phases into the sporophyte and gametophyte through the processes of meiosis and fertilisation. To better comprehend the plant’s life cycle ... The bryophyte lifecycle consists of alternating generations between the haploid gametophyte and the diploid sporophyte.

WebUnlike vascular plants (i.e., tracheophytes), in bryophytes the haploid gametophyte generation serves as the primary stage for photosynthesis and growth and the diploid sporophyte, which is nutritionally dependent on the gametophyte, performs reproductive and dispersal functions. WebThe sporophyte of bryophytes is called sporogonium which generally consists of a single, terminal sporangium (monosporangiate) with a bulbous foot and with or without an unbranched stalk or seta. The sporogonium is very delicate, short-lived and nutritionally dependent on its gametophyte.
