Answer:
The electrical impulses generated in the nerve cells will reach only those cells that are connected by nervous tissue, not each and every cell in the animal body. Also once an electrical impulse is generated in a cell and transmitted, the cell will take some time to reset its mechanisms before it can generate and transmit a new impulse. Thus cells cannot continually create and transmit electrical impulses. Therefore multicellular organisms require another means of communication between cells, namely, chemical communication.
