4. 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.

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!
