The upper part from the original photograph from the study: in both photographs, animal cells from two populations are visible - one was colored red and the other green. The purple color paints the cell cytoplasm, while the green color paints the cytoplasm and the cell nucleus, which is seen as a circle with a denser color in the cells. In the top photo, each cell maintains its separate identity. Credit: Technion barges.

The lack of ATP in the cells of Escherichia coli causes them to take on an elongated shape and form compact lipid structures called endoliposomes. These structures can be clearly seen in the images presented here obtained with the help of a TEM microscope.
