Cyanobacteria vs. Algae: What’s Really Under the Microscope?

[@ronaldkessel2776]

Thanks! I'm seeing these a lot and finally know what they are.

I loved to see the oxygen “growing”!

Thanks for clarifying for the public and note that Cyanobacteria produced the molecular oxygen and the petroleum that we are consuming resulting in a diminishing atmosphere which allows more UV energy to reach the Earth's surface where it transitions to light and then heat.

If you have some water-bound fungi and cyanobacteria that are a little symbiotic at what point might we start calling it a lichen community? I suppose a lichen ought to be stuck to something like a rock... but it seems possible that there are just floating globs of codependent bacteria and fungi that together act almost as one organism... hmmm

Great video! I just subscribed. How do they do photosynthesis without organelles? Isn't chloroplast an organelle? Or do organelles only mean things like the nucleus?

[@Microbehunter]

The cyanobacteria do photosynthesis without organelles. Plants and others eukaryotes have chrloroplasts, which are organelles. And these chloroplasts were originally cyanobacteria that moved into a host cell to do photosynthesis inside the cell (endosymbiosis).

@@Microbehunter Thanks! that makes more sense. I didn't realize that's what cyanobacteria were!

[@davidgoldstein2890]

I think you left out one of the most important points about Cyanobacteria. If I am not mistaken, current theory holds that they are responsible for transforming the earth's atmosphere some 2-3 billion years ago from one that was virtually oxygen free to its current oxygen rich status (approx. 21%).

Wow
