Another similarity is that both mitochondria and chloroplasts contain some amount of DNA (though most DNA is found in the cell's nucleus). Chloroplast dimorphism between BS and M cells has long been recognized (Rhoades and Carvalho, 1944; Laetsch and Price, 1969; Laetsch, 1971).BS chloroplasts generally are larger than those of M cells and, where quantitative data have been gathered, are more numerous per cell and occupy a greater fraction of cell cross-sectional area (Liu and Dengler, 1994; Dengler et al., 1996; Ueno, 1996b). It is oval or biconvex, found within the mesophyll of the plant cell. The size of the chloroplast usually varies between 4-6 µm in diameter and 1-3 µm in thickness.
