spore producing plant generation. The dominant generation in pteridophytes and higher plants and alternates with the gametophyte generation.
the Sporophyte generation
Gametophyte-haploid Sporophyte-diploid
In moss, where the sporophyte grows directly out of the top of the gametophyte.
The gametophyte has become smaller, and the sporophyte has become larger. To begin with main plant body was gametophytic and sporophyte was dependent on it. Later on, as the evolution progressed, both gametophyte and sporophyte became independent and ultimatly gametophyte became dependent on sporophyte.
Three examples of a sporophyte are Polypodium, mosses, and a pine tree.
gymnosperm- sporophyte angiosperm- sporophyte
The sporophyte stage depends on the gameophytestage because the gameophyte stage has a photosynthic stageand because the sporophyte stage lives shortly.
The cap like structure on the capsule of the sporophyte generation in a bryophyte is the operculum. The structure that covers the capsule of the sporophyte in bryophytes is calyptra.
It does not depending on sporophytes generation
Flowering plants do not have a sporophyte. They have antheridium and archegonium to produce their gametes. Sporophyte is found in ferns, mosses, club mosses, lycophytes, etc but not in flowering plants. Flowering plants produces pollen while a sporophyte produces spores
The sporophyte stage depends on the gameophytestage because the gameophyte stage has a photosynthic stageand because the sporophyte stage lives shortly.
In plants, what is the diploid form called?
