As a new member of this marvellous micro-meetingplace I want to present an appetizer.
Last time i got a green algae namend Eremosphaera viridis in focus. Plasma was sligthly condensed, almost all the chloroplasts show their pyrenoid covered with amylum.
I use an old Zeiss Universal. This picture was taken through a Planapo 63/1,4 and Olympus C7070 CCD camera. Three shots stacked manually with Photoshop (controlled stacking without uncontrolled artefacts )

Enjoy your meal!

Some explanations:rjlittlefield wrote:Wolfgang, this is a wonderfully detailed picture!
But I confess, I'm not sure what I'm looking at.
I presume this is a single cell with many chloroplasts.
But what are the many filaments that appear to be connecting the chloroplasts with the outer membrane?

Eremospharea is a unicellar green alga. Yes, the green crumbs you see in the cellular lumen are chloroplast, each of them with a grain named pyrenoid which produces amylum for reserve.
Eremosphaera usually lives in sphagnum ponds. A more common perspective is demonstated at Protist Information Server. Look at

Perhaps you remember...
So long, Wolfgang
