Five images. Optical journey into the interior of the cell.

First:	Synoptic representation of the cell outline, the alate chloroplasts and the cell wall covered with tubercles (tiny knobs).
Second to fourth:	Series of optical cross-sections through the cell showing chloroplast wings.
Fifth:	Deepest optical section plane with cell nucleus and pyrenoids. Note the representation of the mucilaginous sheeth around the cell.
