What do the moss life cycle and the fern life cycle have in common?
A
Both reproduce primarily through seeds.
B
Both have a dominant sporophyte stage.
C
Both exhibit alternation of generations.
D
Both have a dominant gametophyte stage.
Verified step by step guidance1
Understand the concept of alternation of generations, which is a life cycle that alternates between a multicellular haploid phase (gametophyte) and a multicellular diploid phase (sporophyte).
Recognize that both mosses and ferns exhibit alternation of generations, meaning they have both a gametophyte and a sporophyte stage in their life cycles.
Identify that in mosses, the gametophyte stage is dominant, meaning it is the most visible and long-lived stage of the life cycle.
Identify that in ferns, the sporophyte stage is dominant, meaning it is the most visible and long-lived stage of the life cycle.
Conclude that despite the differences in which stage is dominant, both mosses and ferns share the characteristic of having alternation of generations in their life cycles.
