Plants have no brain or central nervous system, which means they can't feel anything. But let’s dive a bit deeper.

Humans and animals perceive pain through sensory nerve cells. These are the same type of cells that transmit information from our senses, allowing us to smell, see, hear, taste, and touch. These cells are part of what’s called the peripheral nervous system, which includes all the body's nerves except those in the spinal cord and brain.

Peripheral nerve cells form a network that carries messages from the skin, muscles, and organs to the spinal cord and brain. The brain responds by sending back messages to the pain site that promote the healing process.

So what does all this have to do with plants? Well, biologists know that neural systems like ours and those of other
animals (yes, fish included) are one way to process information
but not the only way. Even though plants don’t have nervous systems, they can respond to stimuli. For example, when an aphid attacks a leaf, this sends an electrical signal that goes from leaf to leaf to tell the plant to start protecting itself. But it’s important to note that responding to damage does not mean the plant is in pain.
