Paramecium bursaria, final moment of transverse fission
These four panels show the "Christmas Paramecium" I posted the other day (http://www.photomacrography1.net/forum/ ... .php?t=834) at the final moment of reproducing by fission.
1) Gives an overview where it can be seen that the process is nearly complete.
2) Shows a closer detail at about the same stage as 1
3) The last moment. As the two organisms moved apart, the cell wall stretched sort of like taffy or silly putty
4) The connection suddenly "broke" and here you can see the points of connection as they move toward each organism. Within a second or two, these points were gone and the cell wall looked rounded and smooth.
2, 3, and 4 taken with 40X objective, 3.3X photo-eyepiece. Oblique bright-field with crossed polarizers. Canon 10D. Electronic flash. (1 taken with 20X)
Often I have wondered about this final phase of division. I have never been able to see it this clearly until now. Thanks Charlie

Steve... It's the same one. These pictures were taken about 20-30 minutes after the one I posted originally. If you take another look at that one (http://www.photomacrography1.net/forum/ ... .php?t=834) you can see the division just barely starting. (As that eagle eye Ken pointed out )
