	anabaena spec. botanical garden, university Duesseldorf August 2006	The picture shows an anabaena spec. with cells in different cell-division stages. You can see also the somewhat bigger heterocystis in the middle of the filament. Here the nitrogen processing takes place. At the contact points with the "normal" cells there are two light scattering granules visible. These are the so called pole-bodies. Through these the nitrogen-assimilates are transported to all other cells.. Microscopy, Stereomicroscope, Microfoto

	nostoc-(anabaena)-azollae river Erft near Frimmersdorf April 2003	The right picture shows the algae nostoc-(anabaena)-azollae. The pictures to the left show the fern azolla filiculoides. It forms a symbiosis with the cyanobactrium which is living in caves formed by the ferns leaves.

	oscillatoria species garden pond, April 2004	Oscillatoria is able to move by rotating around the longitidinal axis.
	scytonema spec. Cologne-Wahn, moor January 2007	The genus Scytonema shows false branchings. This means, that the branch is generated from two independent filaments and not by the cells of a single filament. Furthermore there are three heterocysts visible. Heterocysts are special cells that are able to synthesize organic (nitrogen) compounds from the nitrogen in the air. Also visible is the common mucous borderline.
