According to the phylogenetic tree in Figure 28.5, which of the following clades is the sister group to Plants within the Archaeplastida supergroup?

  • A: Green algae
  • B: Chlorophytes
  • C: Charophytes
  • D: Red algae

Explanation

In a phylogenetic tree, sister groups are two lineages that diverge from the same common ancestor. Within the Archaeplastida supergroup, the tree clearly shows 'Charophytes' as the direct branch that is sister to 'Plants', indicating they are their closest relatives among the groups shown.
