Chapter 21, Problem 6SQ
Summary Introduction
Introduction: Most of the protists have a chloroplast. Primary endosymbiosis results in the evolution of the first chloroplast. Chloroplast has evolved from other protists by the secondary endosymbiosis. The initial chloroplasts have two membranes, and the chloroplasts that are evolved through the secondary endosymbiosis process consist of four membranes. Green algae have the chloroplast that contains both chlorophyll a and chlorophyll b.
