So mitochondria reproduces at the same time as the rest of the cell?

Thank you. I also added another picture I found on the web, perhaps those two are related?

@Remi.b Right!!! I'm sorry. Yes I'll upload it again, however it is from a different sample

@Tytoalba Pond water... very dirty pond water

@Remi.b I added that the zoom is 40x. It didn't move, at least not enough for being noticeable. I agree that I need to study about the diversity of single celled organisms, but why do you say eukaryotes? is that a hint? I thought it had to be a procaryote since it sort of look like a very long bacillus. Also, I was convinced it was cyanobacteria, but now I doubt it

@James, sorry I thought of writing something else, but since this was an analogy I didn't know what else to put. Is it necessary to delete this?
