From the C-fern illustrations that you collected during lab throughout the semester, select the illustrations that best represent the sequential stages of growth of your C-fern; beginning with the germinated spore and ending with the young sporophyte individual. Arrange the illustrations you selected in a sequence that illustrates GRAPHICALLY (do not write sentences or paragraphs to explain the stages) the growth, development and reproduction of your C-fern. Each illustration of each growth stage will require a concise legend in order...

Phylum Hepatophyta:
Liverworts
Like the moss, liverworts begin as a haploid spore. As a
liverwort spore germinates, it develops into a flat, lobed,
leaf-like structure called a thallus. The thallus
grows prostrate with the ground’s surface, forming
rhizoids that anchor it in place.
Liverworts reproduce asexually primarily by
fragmentation; however, some liverworts may also
reproduce asexually by bundles of tissue called
gemmae. In many liverworts, gemmae develop in
small cup-like structures called gemmae cups.
Splashed from the cups by rain,...
