Mougeotia, an Alga

Post by NikonUser »

An interesting alga. Cells are cylinders each about 66µ long.
Top shows chloroplasts in 'face' view, bottom in a side view; see following text.
Nucleus can be seen as a clear circle between the 2 chloroplasts in the lower cell in bottom image.

"Each Mougeotia cell has one or two plate-like chloroplasts that can rotate to maximize light levels. Each chloroplast has multiple pyrenoids that are either scattered or arranged in a row. Sensory pigments detect the wavelength and position of the light. A transducer translates this information into a chemical code that signals a mechanical effector to move the chloroplast, much like a mechanized solar panel."

” I suppose you are an entomologist ? “
” Not quite so ambitious as that, sir. I should like to put my eyes on the individual entitled to that name.
No man can be truly called an entomologist,
sir; the subject is too vast for any single human intelligence to grasp.”

Great photos and thanks for the two different views. The cells look different and harder to ID when you just have the thin version versus the ribbon view.

First rate photography, and a great explanation of how they work. Mother Nature always invents things first, then man takes the credit. LOL
