Question

Cells are very small in size give reason

Answer 1

Explanation:

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.

from wikipedia

Answer 2

Answer:

Cells need to be small because they need a high ‘surface to volume’ ratio, which is good for exchanging materials between the inside and outside of cells.I think cells are small because membranes are weak. If the cell gets too big, the cell will fall apart.
