sporophyte

[spôrə-fīt′]
  1. Among organisms which display an alternation of generations (such as plants, fungi, and certain algae), the individual diploid organism that produces spores. A sporophyte develops from an embryo resulting from the union of two gametes. Each of its cells has two sets of chromosomes, as opposed to the haploid gametophyte generation.
