Figure 2. Plasmodium falciparum with its chloroplast-related organelle, the apicoplast. Here the morphology of the apicoplast is shown throughout the asexual life cycle of the blood-stage plasmodium parasites through the use of green fluorescent protein (GFP). The single apicoplast in A enlarges and elongates to form the branched forms shown in D. They divide (E) and segregate into the free merozoites in F.
