Adrenaline is secreted into the blood, reaching all cells of the body, and inducing widespread changes. This contrasts with relying solely on electrical impulses, which would have a more limited range of tissue instructions.

Abscisic acid is beneficial for a plant in situations where growth needs to be restricted. Its inhibition of growth, leading to effects like wilting of leaves, can help the plant conserve resources during periods of stress or unfavorable environmental conditions.

Plants regulate growth through hormones like abscisic acid, which inhibits growth. The effects of abscisic acid include wilting of leaves.

Multicellular organisms utilize chemical communication because it overcomes the limitations of electrical impulses, allowing for widespread and continuous signaling to coordinate various cellular activities in the body.

Cells take time to reset their mechanisms after generating an electrical impulse, preventing them from continually creating and transmitting impulses.
