Desmids are green algae you can find exclusively in fresh water. Most
are unicellular, 
and are divided into two parts separated by a narrow
bridge or isthmus. Desmids have
a variety of highly symmetrical and
generally attractive shapes, which provide the basis
for their
classification. Each part of the cell has one chloroplast. Sexual
reproduction occurs through a process of conjugation, but more often
they reproduce by simple cell division
On the pages I present here you can see my collection of Desmid pictures.
All desmids shown on the picturesare found in the Dutch province of Drenthe.
