What are SRPs. What are the doing?

 

 

Secondary endosymbiosis (more than one might be correct!)
A) gave rise to the chloroplasts of red and green algae
B) is a symbiosis with an endosymbiont, which in turn already had an endosymbiont
C) sometimes is revealed by the presence of a nucleomorph sandwiched in the plastid envelope
