Given that plants do not have pain receptors, nerves, or a brain, they do not feel pain as we members of the animal kingdom understand it. Uprooting a carrot or trimming a hedge is not a form of botanical torture, and you can bite into that apple without worry.
Plants do not have pain receptors, which is a critical sign that plants do not experience pain in the same way that animals do.
While the scream of the mandrake is mere legend, scientists have now discovered that plants do indeed emit screams when they are cut or are dehydrated. And unlike the mandrake's scream, which was believed to be fatal, the sounds that come out of plants when they suffer can only be heard by some animals and insects.
Although plants don't have nerves, plants cells are capable of generating electrical impulses called action potentials, just as nerve cells in animals do.
According to a new study from the University of Missouri, plants are able to sense when they are being eaten and utilize defense mechanisms in an attempt to prevent it from happening. Plants recognize the sound of herbivores feeding on their leaves, and then use their tissues to send our vibrations.
Plants can sense and react to more aspects of their environments than we can, and they maintain bustling social lives by communicating with each other above and below ground. They also interact with other species.
Since the human genome was first sequenced in 2003, the field of comparative genomics has revealed that we share common DNA with many other living organisms — yes, including our favorite yellow peeled fruit.
While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.
During their lifetime, trees are not only able to adapt quickly to new conditions but can even pass on the 'memory' of such environmental changes to the next generation. This amazing ability has been proved for the first time by researchers at the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL).
Trees are a lot like people: they experience stress and they get infected with bugs or diseases and they can be attacked by fire, windstorms, floods, and droughts. We call these things that attack or infect trees disturbances.
If something hurts humans, we react instinctually to it—“fight or flight”—as do other animals. But plants don't have that ability—nor do they have nervous systems or brains—so they may have no biological need to feel pain.
A study, published in the peer-reviewed journal Cell on Thursday, found that plants can emit high-pitched clicks when they are stressed by droughts, infections, or cuts. These noises are at about the volume of a normal human conversation, but they are so high-pitched that we cannot hear them.
No, plants cannot feel emotions because they do not have complex consciousness, intelligence, or anatomical systems to process and react to feelings. Plant neurobiologists have argued that plants display some evidence of a simple level of consciousness.
There is also fairly robust evidence that plant cells can perceive and respond to pressure waves, like the kind that are generated by sound in the environment and touch — like, say someone walking up to a tree and hugging it.
Neurobiologists have long recognized that fish have nervous systems that comprehend and respond to pain. Fish, like “higher vertebrates,” have neurotransmitters such as endorphins that relieve suffering—the only reason for their nervous systems to produce these painkillers is to alleviate pain.
Research has clearly shown that lobsters, crabs, and other crustaceans can and do experience pain. Scientists have shown that their reaction to painful stimuli is more than just a reflex response and instead, they learn from painful stimuli and change their behavior.
Orchids are sometimes called "the smartest plants in the world" because of their ingenious ability to trick insects and people into helping with their pollination and transport.
According to research, while trees may not sleep in the same way animals do, they do relax their branches during nighttime, which suggests that yes, trees have activity-rest cycles. These cycles can also vary depending on the tree species.
Plants are much smarter than we give them credit for. They sense their environment, process information, communicate, and problem solve to some extent. Nevertheless, there is a limit to how smart or aware they can be without the nervous systems we animals thrive on.
The wild wriggling and squirming fish do when they're hooked and pulled from the water during catch-and-release fishing isn't just an automatic response—it's a conscious reaction to the pain they feel when a hook pierces their lips, jaws, or body.
The slaughter process has two stages: Stunning, when performed correctly, causes an animal to lose consciousness, so the animal can't feel pain. The law states that, with few exceptions, all animals must be stunned before 'sticking' (neck cutting) is carried out.

We know the genetic difference between sexes is around one in 20,000. We know chimps and bonobos share 99% of our genes. More startling is an even newer discovery: we share 99% of our DNA with lettuce.
The chimpanzee and bonobo are humans' closest living relatives. These three species look alike in many ways, both in body and behavior. But for a clear understanding of how closely they are related, scientists compare their DNA, an essential molecule that's the instruction manual for building each species.
"You share 50 percent of your DNA with each of your parents. But with bananas, we share about 50 percent of our genes, which turns out to be only about 1 percent of our DNA," emails Mike Francis, a Ph. D. student in bioinformatics at the University of Georgia.
