sporophyte -- The diploid stage in the life cycle of an organism undergoing an alternation of generations. The sporophyte is multicellular and develops from a zygote.

sporophyte The diploid, spore-producing plant in the alternation of generations; undergoes meiosis to produce the haploid spores.
sporoplasm Amebalike portion of a microsporan or myxosporan cyst that is infective to the next host.
Rabe and Haufler (1992) found a naturally occurring diploid sporophyte of maidenhair fern which produced unreduced (2N) spores. These spores resulted from a failure of the paired chromosomes to dissociate during the first division of meiosis.
Sporophytes are the reproductive structures you will find in mosses. They are actually a phase of the moss life cycle that feeds off the green parent plant (the gametophyte).
In higher plants, the diploid generation, the members of which are known as sporophytes due to their ability to produce spores, is usually dominant and more recognizable than the haploid gametophyte generation.
flower - a shoot of the sporophyte of a higher plant that is modified for reproduction and consists of a shortened axis bearing modified leaves; especially, one of a seed plant differentiated into a calyx, corolla, stamens, and carpels (Webster) ...
(Science: plant biology) A haploid spore produced by a plant sporophyte that develops into a male gametophyte. In seed plants, it corresponds to the developing pollen grain at the uninucleate stage.
The haploid stage of a plant life cycle that produces gametes (by mitosis). It alternates with a diploid sporophyte generation.
