c. gametophyte

d. zygote

Q359: Draw a

phylogenetic tree that represents our current understanding

of evolutionary relationships between a moss, a gymnosperm,

a lycophyte, and a fern. Use a charophyte alga as the outgroup.

(See Figure 26.5 to review phylogenetic trees.) Label each

branch point of the phylogeny with at least one derived

character unique to the clade descended from the common

ancestor represented by the branch point.
