Why is there a limit to cell size in multicellular organisms?
As size of cells increase, their surface area to volume ratio also increases meaning substances would diffuse too slowly into the cell.
As size of cells increase, their volume decreases meaning substances would diffuse too slowly into the cell.
As size of cells increase, their surface area to volume ratio decreases meaning substances would diffuse too slowly into the cell.
