Releasing a chemical compound enables diffusion around the original cell, potentially reaching all cells in the body. This chemical communication can be slower but reaches cells beyond nervous connections, ensuring steady and persistent transmission of information.

Most multicellular organisms use chemical communication between cells due to the limitations of electrical impulses, ensuring broader communication beyond cells connected by nervous tissue and allowing for sustained signaling.

Cells require time to reset their mechanisms after generating and transmitting an electrical impulse, preventing continuous creation and transmission of such impulses.

Electrical impulses are rapid means of information transfer in animal bodies. Limitations include the constraint of reaching only connected cells through nervous tissue and the need for cells to reset before generating new impulses.

The sensitive plant exhibits quick movement in response to touch, sunflowers show relatively slow movement in response to day or night, and growth-related movements in plants are even slower.
