Three images.

First:	Synoptic representation of the cell wall. Especially in the upper part of the picture, the existence of the gelatinous sheath is impressively illustrated by the symbiotic bacteria embedded in it.
Second:	Optical cross-section through the chloroplasts showing some of their lobes and storage substances (fat droplets called oleosomes).
Third:	The optical cross section through the cell shows the two pyrenoids and storage substances (oleosomes). In the pyrenoids, the cell produces the storage substance starch.
