Species of the unicellular algal lineage Euglena have chloroplasts surrounded by 3 membranes, while land plants and green algae have chloroplasts surrounded by 2 membranes. On your handout, draw a detailed diagram/flow chart that demonstrates how this could have happened, starting with the pre-chloroplast ancestor to Euglena, and the photosynthetic cell that it engulfed. Draw any nuclei if present. Be sure to indicate the origin of each membrane. No need to write anything below. But you can tell me something silly you did recently if you want!
