No, plants cannot feel pain. There is no possible way for that to happen without a central nervous system.
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.
Although plants don't have nerves, plants cells are capable of generating electrical impulses called action potentials, just as nerve cells in animals do. In fact, all biological cells are electrical. Cells use membranes to keep their interiors separate from their exteriors.
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.
They don't have nervous systems, but they can still feel what's going on, and experience something analogous to pain. When a tree is cut, it sends electrical signals like wounded human tissue.”
In short, plants possess a highly developed, conscious root brain that works much as ours does to analyze incoming data and generate sophisticated responses.
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.
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.
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.
JONATHAN BIRCH: There's evidence that a lobster will carry on living for two to three minutes when it's dropped into a pan of boiling water and that the nervous system response carries on very intensely during that time, just as it would with you or me or a cat or a dog or any animal dropped into a pan of boiling water ...
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.
And since plants do not have brains, nor a central nervous system (which is how intelligence is defined), it is said to be impossible for them to have emotions and the ability to reason or feel.
Oysters have a small heart and internal organs, but no central nervous system. Lack of a central nervous system makes it unlikely oysters feel pain, one reason some people who otherwise are vegetarians comfortable eating oysters.
First, make a shallow cut on the underside of the branch, one or two inches beyond the branch collar. This will act as a barrier, preventing a bark tear if the branch falls while being cut. Second, cut through the branch two to four inches beyond the branch collar, removing the branch and leaving a stub.
Trees absorb and store carbon dioxide. If forests are cleared, or even disturbed, they release carbon dioxide and other greenhouse gases. Forest loss and damage is the cause of around 10% of global warming. There's simply no way we can fight the climate crisis if we don't stop deforestation.
So, do sharks feel pain? Yes – but it is different to how we express pain . Sharks do not have the same nervous system as mammals but what we do have in common are neurons called nociceptors. These receptors are designed to detect potential harm – such as temperature and pressure.
Cows experience pain during parturition, dehorning, lameness and when injured or sick. Among humans, different people have different pain tolerance, and the same may be true for dairy cows.
Here is a news article I found on the topic: Worms on a Hook Don't Suffer? OSLO (Reuters) - Worms squirming on a fishhook feel no pain -- nor do lobsters and crabs cooked in boiling water, a scientific study funded by the Norwegian government has found.
Cow cries before slaughter. They sense their final destiny. Don't be a reason behind their suffering.
Do pigs cry when slaughtered? The sound of pigs screaming can be heard echoing throughout the walls of slaughterhouses and even factory farms. Their cries are loud and piercing: clear signs of distress.
They were stressed, petrified and piled up on top of each other. While waiting to be killed, the animals screamed in agony as they wounded themselves on the metal gratings. When animals are slaughtered, they are not completely stunned and are still aware of what is happening.
Trees lack a nervous system, so they can't experience emotions that we feel, like happiness or excitement.
Spending time around trees and looking at trees reduces stress, lowers blood pressure and improves mood. Numerous studies show that both exercising in forests and simply sitting looking at trees reduce blood pressure as well as the stress-related hormones cortisol and adrenaline.
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.
