Question 14

Hornwort sporophytes have a basal region of cell division rather than an apical region.What effect does this have on sporophyte function in hornworts,as compared with mosses?

Accepted Answer

D)  It keeps making green tissue to support growth of the gametophyte,while in mosses the gametophyte supports the sporophyte. 
E)  It helps raise the spores so they can be more easily dispersed by symbiotic fungi,while in mosses the spores are dispersed by wind.
