WebBranched Sporophyte. The sporophytic axes, or stems, of vascular plants are different from those of liverworts, hornworts, and mosses in that they are branched and bear multiple (not just one) sporangia. Extant vascular plants share this apomorphy with some fossil plants that are transitional between the “bryophytes” and the tracheophytes.

The sporophyte develops from the zygote produced when a haploid egg cell is fertilized by a haploid sperm and each sporophyte cell therefore has a double set of chromosomes, one set from each parent. All land plants, and most multicellular algae, have life cycles in which a multicellular diploid sporophyte phase alternates with a multicellular haploid gametophyte phase.
