Question

Why do Multicellular organisms need another means of communication between cells besides nervous coordination i

Answer 1

"Multicellular organisms need another means of communication between cells besides nervous coordination because there are multiple cells in the body and it is not possible for the nervous tissues to reach to each cell.

Another reason which spurs on another means of communication is that it becomes difficult for the nervous tissues to transmit messages continuously, which they fail in, hence they need to rest to reset and then continue.

"

Answer 2

Answer: Multicellular organisms need other means of communication because:

• We have many cells in the body. The neurons and nervous tissues can't reach every cell of the body. Therefore Hormones are also used as a mean of communication.
• Another reason is because the nervous tissue cannot be working all the time and need rest. At this time the hormones are used for communication as they flow in blood and do not use energy
