Question

why are the cell usually small​

Answer 1

$\huge\underline\frak{\fbox{AnSwEr:-}}$

The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

That is why cells are so small.
