Idk enough on the subject to even start here. However, if your responding to someone in all caps and multiple HAHA’s. You’re probably already wrong in one way or another…
HAHAHAHA GLOBAL WARMING’S EXISTENCE WAS CALLED INTO QUESTION EXCLUSIVELY BY THE ACTIONS OF FOSSIL FUEL COMPANIES SEEKING TO POLITICIZE AN EXISTENTIAL THREAT TO HUMANITY FOR THE SAKE OF SHORT-TERM PROFITS. CHECKMATE, ATHEISTS.
they’re actually called red blood not cells.
Oh my god… I get it
Blood cells were invented by Johnny Hemoglobin in 1912.
This is why I don’t trust big hemoglobin; it’s all a conspiracy to sell more blood and make the board of directors wealthy.
A little light reading on the subject. But then I lost interest.
https://biology.stackexchange.com/questions/17295/why-are-red-blood-cells-considered-to-be-cells
So if i understand correctly, they initially have a nucleus but after the nucleus produces all the required proteins, it’s ejected.
That’s why it takes so long to regenerate them after a blood donation. Production speed is limited so all those ejected nuclei don’t set off a chain reaction and turn you into a fission bomb.
You underestimate my power
KAAANEEEDAAAA!!!
So they are “cells” as in prison for oxygen molecules?
Red blood cells aren’t considered true cells.
Biologist here. Erythrocytes are cells. Not sure where you got “true cells” from.
No True Scotsman/Cell.
No true cellsman.
HI BILLY MAYS HERE. HAVE I GOT A NUCLEUS FOR YOU
Thanks for the clarification, from my limited knowledge and research they are a specialized type of cell… So kinda wrong to say categorically that they are not cells. Correct?
Yep! You’re totally correct. They’re indeed highly specialized, it’s a chain that starts with a proerythroblast that would look more like a “normal” cell going all the way to the erythrocyte, the familiar red blood cell.
Very frequently in biology we create definitions and groupings that get more and more specific, but without taking away from the original group: for instance, carnivores are a specific group of animals with specialized characteristics… But they’re still mammals. And mammals are still animals. And animals are still Eukaryotes. And so on.
Cells do not follow the same type of definitions that we would use for groupings, but the logic still applies - losing a nucleus won’t make this cell suddenly not a cell. In fact, the membrane is still highly dynamic, there are still internal and external communication mechanisms, and there’s a metabolism - glycolysis.
If you’re not already a teacher/lecturer you’d make a great one!
They don’t have the organelles or nucleus that most cells do have. They can’t replicate.
I mean like most fields it depends on your definition. It doesn’t help that many people are taught they aren’t “true” cells.
they don’t have the organelles or nucleus
What exactly they lose depends on the species, human red blood cells indeed discard organelles and the nucleus.
But having organelles and a nucleus are not the formal definition of a cell. To begin with, any prokaryotes won’t have a nucleus, and organelles aren’t mandatory.
Tell that to the oxygen molecules
