ling 10. Explain the mechanism of spore dispersal in ferns with sori 11. In what way is this mechanical method of spore dispersal similar to that in the bryophytes? Most ferns produce only one kind of spore and are therefore homosporous. Upon germination, the spore, the first cell of the gametophytic generation, gives rise to a heart shaped, bisexual gametophyte, called a prothallus. 12. What type of nuclear division produces the many celled gametophyte from a spore?
