Sporophyte: 1. It is an independent plant with diploid chromosome number. 2. In algae, the sporophyte is confined to zygote. In bryophytes, the sporophytes are a complex structure but is dependent on gametophyte. 3. In pteridophytes, gymnosperms and angiosperms the sporophyte is dominat. 4. In lower groups of plants, sporophyte reproduces by spores spores that give rise to gametophyte. 5. In higher plants sporophyte performs vegetative and sexual reproduction. Gametophyte: 1. It is an independent plant with haploid chromosome number. 2.
