Question

State two limitations of electrical impulses in multicellular organisms. Why is chemical communication better than electrical impulses as a means of communication between cells in multicellular organisms?

Hint:

Chemical signals provide a more coordinated and sustained form of communication in multicellular organisms, enabling complex bodily functions.

Answer 1

Drawbacks of electrical impulses: Electrical signals are restricted to nerve pathways, limiting their reach within the body. Their transmission speed is also sometimes slower than that of chemical signals, making them less suitable for swift long-distance communication.
Advantages of chemical communication: Chemical signals, like hormones, use the bloodstream for widespread distribution, enabling more comprehensive and coordinated communication. While slower, chemical communication offers a more enduring and sustained effect compared to transient electrical impulses.
