What is the size of a cell on Mars?

Answer 1

In most cases it would be so cold, that the fluid mostly made of water inside of it would freeze, and as we all know water expands when it freezes, and that would cause the cell to burst. But in best case scenario it is actually warm enough for a cell to live there.

but temperature is not the only problem pressure is also a concern:

be cause the mass of Mars is significantly less than that of Earth, therefore the gravity of Mars is only 37,7% compared to the Earth's. That's why the atmosphere is much thinner on Mars. it's simply not able to hold on to that many molecules.

Be cause the pressure is based on the number of molecules, the pressure is much less on Mars than on Earth about 100 times actually.

So if the cell were to be thrown out of the space ship with earth pressure, the cell's non-solid content would expand 100 times, and cause it to burst, BUT if the cell were gradually "getting use to" the pressure of Mars, it would be able to sustain its content and actually not increase in size.

In conclusion: the cell would keep its normal size, under the right circumstances that is, but it would only weigh 37,7% of its weight on Earth.
