  Mitochondria are so much more than that!

  They have the ability to kill the cell as well as provide power, they can communicate and transfer resources to other mitochondria, and they might be one of the reasons that organisms need sleep.

  I heard a science communicator suggest that in some senses, we might just exist to serve the needs of our mitochondria.

    Scientists theorize that the mitochondria was an entirely different organism which was captured by our ancient single-celled ancestor and assimilated into itself. I can’t remember what the evidence is for this theory but it’s wild to think about.

      Yep! It's called primary endosymbosis and it's one of the coolest things around! (I think.) The endpoint of a process where two parts of symbiotic relationship morph into an organ in an organism.

      The first case of primary endosymbosis resulted in the mitochondria and thus all multicellar life. That's pretty cool.

      Another time created the chloroplast and thus all plantlife. Again, yay for primary endosymbiosis!

      A few years ago scientists discovered that it happened really recently, resulting in an organism with a "nitroplast" for in house nitrogen fixing. So in the far distant future there could be an entirely novel branch of life, potentially as different from what we know as redwoods are from cats.

      Mitochondria have thier own DNA, and I think that is the reason for that theory.

  it always bugs me that this phrase isn’t even grammatically correct. mitochondria is plural. it should be “the mitochondrion is the powerhouse of the cell”

    Pedantry gone too far!

    Mitochondria would be grammatically correct because there are multiple mitochondrion in the cell. Referring to only one of them would be inaccurate.

      Then it’s the mitochondria are the powerhouse of the cell

    It’s kinda like like the plural form has also become a colloquial singular form

    Same with “a bacteria”

    mitochondria are the powerhouse of the cell

  • lugal@lemmy.dbzer0.com ⁨10⁩ ⁨hours⁩ ago

    That makes it sound like each cell has one mitochondrion and each mitochondrion equates to one powerhouse while in fact, all mitochondria of a cell collectively are the powerhouse of the cell

      not necessarily. for example we say things like “the lion is the king of the jungle,” but that doesn’t mean there’s only one lion per jungle. sometimes we refer to an archetypal singular to convey something about every member of a group

    Well…a single mitocondrion is not really a powerhouse of anything except really simple single celled organisms.

    Wikipedia:

    The number of mitochondria in a cell vary widely by organism, tissue, and cell type. A mature red blood cell has no mitochondria, whereas a liver cell can have more than 2000.

    It would be more correct to say “are the powerhouse of the cell”.

  Parasite eve taught me all I needed to know about mitochondria. As well as science. Also there were cig boobs on the eve monster which was pretty cool when I was a horny child.

  What is that phrase actually from? I always thought it was Bill Nye the Science Guy, but I’ve never actually been able to find a clip.

    I was thinking Beakman's World. Apparently it's just such a common phrasing in high school science that it became a meme without anyone's particular influence.

    Middle school science class probably. They probably reiterate it again in highschool biology.

  All I ever think of when it comes to mitochondria is Parasite Eve and spontaneous combustion/mutants.
