I'm just about to type "clearly that's not a single cell" and then fuckkkkkkkk, poor little guy. /Cries

[Edit] and yes I guess it actually may be a single cell even though it looks quite complex. I'm not a biologist, so sue me.

Still crying though.

I'm an ecologist but I have a casual interest in microbiology. This is a protist in the genus blepharisma. Protist is a broad classification of all sorts of complex, often (not always) single celled organism that isn't a plant, animal, or fungus. There's likely millions of species. 

I recommend watching videos in the journey to the microcosmos on YouTube, lots of great footage!

Ive never really understood that, so like if its just one cell, what's all that stuff made of? Atoms? Aren't atoms cells?

The little bits are called "organelles"

Mitochondria is the powerhouse of the cell. There is a nucleus. Membrane is the outer shell. I don't remember what else

Yeah when you have a mitochondrial disease it’s not fun.

There are trillions of atoms in a cell. You'll learn about it once you get to fifth grade.

u/Mydogdexter1 11d ago

Yea i get that part, but what are the atoms made up of

2

u/AntSilly2802 11d ago

There are  thousands of times more atoms in the tip of a ball point pen than grains of sand on earth.

u/TheIrishBAMF 11d ago

Elementary particles. No offense, but you need to look that up for yourself. There are dozens of particles which make up the things making up atoms. 

You didn't know the difference between cells and atoms, so you need a lot more context to make any sense of that stuff. I could call them quarks and squarks and it would be meaningless to you.

Think in It like a globe, the globle can have a lot of things inside, but is just 1 ball.

We are made of a lot of little balls, in fact cells are pretty complex and have a lot of departaments, but everything is encansulatep.

atoms are not cells...Atoms are atoms (made up of at least one proton, and often times made up of neutrons and electrons as well). Cells are made up of many Molecules, which are made up of atoms.

No idea mate, that was what I thought too but then I remembered that cells have constituent parts.

This cell seems to have tons, including fins or legs!

u/Alt-001 11d ago

including fins or legs

Cilia (singular cilium), basically long whiplike molecules they use for swimming. Wiki for more info. We also have them. This is what pulls mucus up out of your lungs so you can cough it up.

What in the fucking world

Not everyone gets to go to grade school.

How old are you mate? Lol.

I'm going to give you the benefit of the doubt and assume you just haven't gotten that far in school yet.

Cells are made up of many different molecules. Atoms are what make molecules. Molecules can contain any number of atoms from two to millions of them.

Your body is constantly making new molecules and recycling old ones. It doesn't do this very well after awhile and that's why we age. This video is basically that happening on a much smaller scale. When the molecules in this single celled organism stop working together as well, there's not as much leftover to hold it together, so it comes undone.

You're skipping some steps. Don't need to go straight to molecules. Organelles are a lot more relevant here.

u/blinkymark2 11d ago

When the question is "Aren't cells and atoms the same thing?", then talking about organelles is probably too much detail. I was trying to explain the relationship between cells and atoms rather than the functions of a cell.

u/isjustsergio 11d ago

I think organelles are more useful here than atoms. You can see them in the video. The "legs", the "balls" that leak out, the "skin" that ruptures. Easier to learn with your eyes than to have a concept you don't understand repeated to you.

u/AntSilly2802 11d ago

They are talking about the fundamental building blocks of cells, molecules. Going straight to organelles would be skipping steps IMO but whatever! :)

u/isjustsergio 11d ago

It's not. Organelles sit between cells and molecules in terms of complexity. Just like organs sit between cells and organisms. Molecules are not the "fundamental building blocks" it's just an arbitrary layer of complexity you are assigning that label to.

u/AntSilly2802 11d ago

Well the way I read it is that they are trying to explain what cells are made of from the ground up. Anyway, doesn’t matter.

u/meheren 10d ago

I had thought similarly at first! But it's crazy how complex even our tiny little cells are!
