Chloroplasts are the ancestral members of a structurally diverse family of organelles known as plastids (which also includes proplastids, amyloplasts and chromoplasts). Plastids are responsible for ...

Malaria and related parasites retain a vestigial, but biosynthetically active, plastid organelle acquired far back in evolution from a red algal cell. The organelle appears to be essential for ...

Scientists found molecular evidence supporting the idea that chloroplasts originated as energy-generating organelles and only later evolved to support carbon assimilation in plant cells. One of the ...

Five different regions of the first foliage leaf of etiolated barley seedlings were studied with respect to leaf growth, plastid growth and replication, differentiation of etioplasts, and conversion ...

Endosymbiosis, a process where one organism engulfs another and integrates its DNA and functions instead of digesting it, is ...
