Question

Does the size of the cells differ from one another

Answer 1

Yes the size of cells differ from one another but it does not differ on the size of the organism.

Answer 2

YES

Cells are the building blocks of life – all living organisms are made up of them. Books often show a single ‘typical’ example of a plant cell or an animal cell, but in reality, the shapes of cells can vary widely. Animal cells in particular come in all kinds of shapes and sizes. Plant cell shapes tend to be quite similar to each other because of their rigid cell wall.

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

Cells have different shapes because they do different things.
