[edit] Summary
I took this image using a digital camera and a compound light microscope at a total magnification of 100X. This is fresh water green algae collected from the scum on the top of a pond in February 2007 in Waxahachie, Texas. The weather had been warm and was turning cold again. I think that it induced these algae to conjugate.
The pointer is showing conjugating filamentous green algae. The two strands are still separate at the bottom where the cells have not yet conjugated. As the strands get closer together a sex pilus is formed and one cell moves across to fuse with the other cell. The empty cell walls in the other strand can clearly be seen.
