Netrium

Post by NikonUser »

I found only 4 images on PMG.net, and not common in my pond samples.
Left image: at mid level showing the characteristic frilly-edged chloroplasts and the central nucleus between the 2 chloroplasts
Right image: surface showing 2 lines of dark green chloroplasts (?). Perhaps these are the outer surfaces of the frilly chloroplasts , assuming the chloroplasts have dorsal and ventral ridges in addition to the lateral ones shown in the left image.

Hi NU,

sorry to keep annoying you, but I am stuck in bed with (?)flu and not much else I can do !!

If you can get the cell end on, you will see that the chloroplast is star shaped *.

I know that Micrasterias is spectacular, but Netrium is a favourite of mine as there is so much detail to see when changing the depth of focus. In wet Sphagnum, I have often found large numbers together.

Thank you for cheering me up with some great photos!
Obrigado,
Brian

Brian: thanks for the comments, keep 'em coming :)
It would take some fancy manipulation to see one of these guys end on, but I understand what you are saying.
