Word Origin and History for sporophyte
Online Etymology Dictionary, © 2010 Douglas Harper
- 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.
