Answer: Larger cells would become limited by the ability to move materials across the plasma membrane.
Explanation:
The larger size of the cell will not aid in the movement of particles across plasma membrane.
Larger size of the cell will disrupt the membrane integrity of the cell which will will not move the materials across plasma membrane.
The smaller particles are moved across the membrane by diffusion and larger molecules will require membrane transporters.
Hence. cells should not be larger in size.
