Question

What would happen if all the cells of our body were of the same shape and size?

Answer 1

Cells are of different shape, size and structure according to the function they need to perform. So, if all the cells become of same size, shape and structure, it will be very difficult for multicellular organisms including humans to adapt better to the environment and survive. Also, the division of labour among the cells will be lost thus leading to difficulties in survival.
