Answer:
Those would have to be some pretty big cells.
Explanation:
Cell transport and other functions of the cell involving movement of fluids and enzymes throughout, especially in terms of waste disposal, heat dispersion, and energy transfer throughout the cell make it more than unreasonable and wholly impossible for a cell to get to that size, not to mention gravity near a celestial body on a cell larger than a microscopic scale would likely break apart, being they are not particularly strong on their own in their cell membranes.
