WebAnswer: Chromoplasts and chloroplasts are part of a developmental family of organelles collectively known as plastids. They appear in plant evolution as endosymbiotic Cyanobacteria. Their incorporation brought photosynthesis and related biochemistry to the original host cell. The progenitor of p... WebChloroplasts are characterized by a system of membranes embedded in a hydrophobic proteinaceous matrix, or stroma. The basic unit of the membrane system is a flattened single vesicle called the thylakoid; thylakoids stack into grana. All the thylakoids of a granum are connected with each other, and the grana are connected by intergranal lamellae.
