Answer:
Step-by-step explanation:
A cell needs to maintain a smaller size because of the following reasons:
Cells different diffuse materials through them via cell membranes. Small cells can easily diffuse materials through them, while larger cells find it difficult.
Cells maintain a small size to maintain the proportionality of the cell surface to the cell volume. *Small-sized cells will have a surface area proportional to the cell volume.
It is easier for the cells with a small size to replicate faster than the cells with the larger size
Cells having small sizes find it easier to be replaced when damaged.
Small-sized cells can have better cell-to-cell communication.
