things you didn't think about
the ostrich egg is the biggest single cell you can find.

as I said, things I didn't think about.
>>8109336
I doubt that's the biggest single cell. What about a neuron in a whale?
Bubble algae is a pretty big single cell organism, not as big as that egg tho.

Are organisms with mitochondria really single celled?
>>8109628
Yes.
A mitchondrion is an organelle.
It cannot survive outside of a cell.
>>8109641
>It cannot survive outside of a cell.
Why not? What's different inside and outside a cell that allows the mitochondria to survive?
>>8109645
Many of their bacterial ancestor's traits have atrophied in Mitochondria.
They just can't, on their own, do all of the things need not continue to not be dead.

Aren't much bigger than yours, there are just much more of them

topkek OP, your knowledge is found lacking, step it up.

I got one:
Provided you had enough copper wire, you could turn the earth moon system into a giant electromagnetic generator, by coiling the moon with the wire and it naturally moving through earth's magnetic field.
The only problem would be the Lorentz force would decelerate the moon and it would collide with the earth eventually.
>>8109336
>the ostrich egg is the biggest single cell you can find.
Maybe at the instant of fertilization, but then the example about whales is a counterpoint, too.
Cells divide within the archetypal egg while is incubated until hatching.
>>8109336
A fucking laid egg is not a fucking single cell
Fucking retard
>>8109645
Because part of the genetic code needed for synthesis of certain proteins for mitochondria is in the Nuclear DNA, and doesn't exist in the mitochondrial dna. Those kind of proteins are synthesized in the cell's ribosomes and then transported to the Mitochondria.
>>8109650
More like the cell cannot survive without mitochondria but can you really say the same about mitochondria? First off, mitochondria has its own DNA which is all that would take for mitochondria to switch to a parasitic intracellular lifestyle which is not that unknown to Rickettsidae, the ancestor of mitochondria.
>>8109714
>having been supplanted by nuclear genes
Actually most of the essential genes that mitochondria depend on are homologous to the T7 phage's genes which are viral in origin.

The yolk is a single cell. It's the ovum.

>More like the cell cannot survive without mitochondria
Wrong. Mitochondria optimize energy extraction, but they aren't the only way for a cell to do it.
>but can you really say the same about mitochondria?
See >>8109650, did I stutter?
>parasitic intracellular lifestyle
>surviving outside of other cells
Pick one, faggot.
>>8110165
aaand where are those genes found? in the nucleus. I'm talking about location, not origins here, but thank you anyway.
>>8110477
>Mitochondria optimize energy extraction
that's not all they do, faggot. there's significant protein synthesis and/or enzymatic activity going on in the mitochondria of most eukaryotes, even in obligate anaerobes.
in fact, when they recently found a protozoan in chinchilla shit that had lost its mitochondria entirely, it was A Big Fucking Deal. and it was only able to accomplish this by acquiring a bunch of bacterial genes to fill the usual mitochondrial roles.
>>8109336
I knew a retard biochemist once and she was quite confident that the human brain is actually a syncytium.
>>8109641
Are obligate parasites still cells?
>biologists
>>8109657
They have multiple nuclei. Just because there's no complete cell wall doesn't mean it's not multiple cells. Many fungi also live this way and they're considered multicellular. They might be considered clonal, or colony forming organisms. Either way, it's not clearly and distinctly unicellular as an ostrich egg is.
Step it up.
>>8109749
>Maybe at the instant of fertilization
A gamete, or egg cell is still considered an organism even if it's unfertilized. As are sperm, the male gamete.

good one
