A lot of the microbes we show you are completely naked, but the test amoeba is a bit more modest.

*Anytime me and my fellow amoeboids are taking the night on the town, we'd always dress in our finest silicate granule clusters and cuticle outer coverings. We were the show stoppers! Then of course, there was always that one streaking amoeba who stole the show, peeling off their proteinaeceous shell and waving it over their cellular membrane and getting the rest of us in trouble! Ah, Good times...*

How a unicellar organism manages to assemble those rather complex shells out of say, two or three thousand particles it gathers from the environment, selects carefully by its shapes and puts all those particles painstakingly together, is a feat which remains quite the mystery to me.

@gurufoxx 4 года назад

Wait...how does a testate amoeba make a little shell for itself without a brain or nervous system? How does it know HOW to do that? And why would it do that without a brain to have the thought about doing that in the first place? And following from that, how do you get reoccurring styles of tests when there is no brain or external communication to create the meme of a test shape or style? MIND BLOWN.

@kf10147 4 года назад

On the smallest scales consciousness isn't required for "decisions" they make a shell because of complex chemical reactions involving proteins that result in a shell. These reactions and proteins exist because of the dna that guides the building/maintenance of the cell. They have that dna bc that's what they are. Life on these scales is so fascinating bc it emerges from the rules of chemistry. If you want to hear more about these concepts I recommend kurzegesagt's videos on consciousness and emergence. They are very well produced and can help you explore these ideas more.

@clray123 4 года назад

@vexingcomos It's not just DNA. Watch video "What Bodies Think About" to see that the morphology of an organism can be modified without messing with its DNA. E.g. you can make a flatworm grow two heads by modifying some electrical fields in its cells. AND - that's the hammer news - the offspring of this worm will have two heads as well - the change is permanent. Or you can make an embryo of the worm develop into a different type of worm altogether.

@thestruggleisreal9626 3 года назад

Nature spent well over 2,000,000,000 years refining the cell. What single cells are, what they do, is far more complex and intriguing than what animals or plants do as a community of such cells.

Danggit, i was really hoping you'd mention the Paulinella genus of testate amoebas, with it's 3 photosynthetic members (Paulinella Chromatophora, Paulinella Longichromatophora, and Paulinella Micropora. There are other non-photosynthetic members though). Outside of the singular event that resulted in chloroplasts, it's the only known case of primary endosymbiosis with a photosynthetic endosymbiont!

@thea_kober 4 года назад

To visualize the numbers on the scale marker better I usually compare them to millimeters, like, 1 mm is 1000 micrometers, so 200 micrometers is 0,2 mm, 500 is half a millimeter, etc. (Idk if this was useful, i suck at explaining things sorry :v)
