Concept

Problem: Now use the phylogenetic tree to determine which statements about secondary endosymbiosis are true.Select that apply. A) Some organisms on the phylogenetic tree acquired mitochondria through secondary endosymbiosis. B) Core Cercozoa and Euglenozoa (locations indicated by the red arrows) acquired their chloroplasts by secondary endosymbiosis from green algae. C) Some organisms on the phylogenetic tree acquired chloroplasts through secondary endosymbiosis. D) The chloroplasts of green algae and glaucophytes are more similar than the chloroplasts of green algae and red algae. (The locations of these organisms are indicated by the purple arrows.)

A) Some organisms on the phylogenetic tree acquired mitochondria through secondary endosymbiosis.

FALSE. From the phylogenetic tree, mitochondria was acquired first before chloroplasts.
