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?
Official answer
Two limitations of electrical impulses in multicellular organisms are:
- They will reach only those cells that are connected by nervous tissue, not each and every cell in the animal body.
- 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.
Chemical communication is better than electrical impulses as a means of communication between cells in multicellular organisms because it allows for the transmission of information to all cells in the body, not just those connected by nervous tissue. Additionally, chemical communication can be more sustained and prolonged, whereas electrical impulses are brief and require time for the cell to reset.

Quick oral answer
Electrical impulses have limitations in multicellular organisms, such as only reaching cells connected by nervous tissue and requiring time for the cell to reset. Chemical communication is a better means of communication between cells because it allows for the transmission of information to all cells in the body and can be more sustained and prolonged.
Common mistakes
- 1.confusing electrical impulses with chemical communication
- 2.not providing clear explanations
Analysis and explanation
The question requires the student to recall the limitations of electrical impulses in multicellular organisms and explain why chemical communication is a better means of communication between cells. The student should be able to identify the two limitations of electrical impulses and provide a clear explanation of why chemical communication is more effective.
Interesting facts
electrical impulses are used for fast responses to stimuli
chemical communication is used for sustained and prolonged responses
