According to who exactly? You'll need some scientific proof on that.

As for that bit about the surface area and volume of a cell, I’ve heard it called the square/cube law; basically, an object’s surface area scales with the square of its length, but the volume scales with its cube, so the latter increases more when an object is scaled up. Just thought they could have explained that better.

Interesting! So the limit to the size of a cell is essentially a trade-off between it's sustenance and waste excretion! 🙂

Finding out that I have a metre long neutron running down my leg kind freaks me out. Oh fuck, I just realised, there's one in the other leg too

There are actually some rather large single celled protozoa dwelling on the Abyssal Plain. Apparently the environment down there is stable (and hostile) enough to allow such fragile creatures to survive.

What about the pseudoplasmodium of coenocytic slime mold? The aggregate form has a single cell wall, and it's capable of basic learning about it's environment (remembering, somehow, interval conditions as an example) and while these usually don't get very big, they can, and they can also subdivide back into separate smaller units.

I've been looking for a video like this! thanks TED-Ed

Fascinating how it convergently evolved fronds like a fern to increase surface area

Why is it that Ted-Ed always ends their videos with some of the most beautiful sentences ever.

Thanks my class had to take notes on this and your voice is very clear so I can hear everything and take notes down. :)

Loved the cell illustration and animation.

Another aspect you didn’t mention is the radical difference in how things move in the microscopic and macroscopic world’s (I think there’d a Ted-Ed about Reynolds numbers, great additional material); the way animals like the elephants and grizzly bears you mentioned eat and move and reproduce involves a whole mess of rigid skeletons and muscles and specialized cells that likely would be impossible for a unicellular creature to mimic, while a cell’s tricks with microtubule “skeletons” and flagellae would not work at macroscopic scales.

3:07 for the answer

Fantastic explanation!

Wonderful clip.I will be delighted if you upload a clip telling how we think or work even we many different cells?

I'm surprised you didn't mention the yolk of an egg as an example of a very large cell.

Now that I know how incredibly thin and delicate my spine to leg nerve cell is, I feel like I’ll be paralyzed any second.

perfect! two cell videos in a row cuz I'm studying it atm.

You know, you could just say “micron”. It’s the same as a micrometer.

I remember an experiment we did in science class once to demonstrate the difficulty presented by volume increasing faster than surface area. We cut 2 cubes of some kind of gel, one big and one small, and out them in a colored water solution and left them over night. When we cut them open the next day, the smaller cubes were mostly saturated but the larger ones were not. This applies to cells because they rely a lot on the passive diffusion of water (osmosis) in order to save energy. It would take a lot of energy to speed up the transfer of chemicals by using a process other than osmosis.

Thanks

Physarum polycephalum, a 'true slime mould', is but one example of a single-celled organism that can easily become 'larger' than 30cm. It can cover up to 1sqm under the right conditions.

I still have no idea why this Square-cube law exists. If you just measure in larger units, then the cube will always have a 6:1 surface to volume ratio.

@drdca8263

6 жыл бұрын

Steve Zukley Sure, but the ratio between the two will be in a larger unit as well. Suppose a "doublemeter" was a name of a unit twice as long as a meter. The ratio between a cubic doublemeter and 6 square doublemeters, would be 1/6 doublemeters, while the ratio between a cubic meter and 6 square meters would be 1/6 meters, and 1/6 doublemeters is twice as much as 1/6 meters. Does that make sense?

If x is the side of cube then volume is (x.x.x), total surface is 6.x.x) ratio volume/surface is x/6. The ratio changes as x changes, not constant as 1/6 as you think.

thanks for the video :)

The reason why there aren't many uni-cellular big organisms is that like it said in the video it doesn't matter if one cell for us gets destroyed (we loose like 37mill everyday) but it will matter for the un-cellular organisms

2:58 you came for this.

Would that mean there is a universal volume and surface area limit to every single cell organism using the same math ratio law you stated in the video?

Phenomenal animation!!!!!!

A cell can be large if it's flat. That makes it fragile, though. There are some algae with cells several feet long.

The cell body of a motor neuron is approximately 100 microns (0.1 millimeter) in diameter and as you now know, the axon is about 1 meter (1,000 millimeter) in length. So, the axon of a motor neuron is 10,000 times as long as the cell body is wide.
