Do plant have nerves? Are they developed enough to feel pain?

To feel pain, you will need a central nervous system and and a brain advanced enough to know that what you are feeling is pain. most plants do not posses a central nervous system, much less a brain. Therefore the plant cant "feel" anything, and is merely a collection photosynthesizing cells among others that chemically react to the photon radiation from the sun light. where ever the radiation is strongest is where the cells will migrate, making the plant appear as though it is consciously leaning toward the sun. If the cells while spreading or "growing" run into an object, they obviously have to grow on or around it since they can grow through it. their are some plants however that do have a collection of simple nerves and motor functions that actually react to touch, such as the Venus fly trap and the sun dew. the nerves aren't fibrous and veiny like the ones in humans and animals, instead they are made of a collection of special cells that are conductive to electrical impulses.

yeah plants can get cancer. i dont think it is as big of an issue for them though, because they dont have critical organs like brain, liver etc that the cancer can infiltrate- just stems and leaves, and the cancer would have to be pretty extensive to kill them off

I honestly didn't think it hurt too badly, but everybody has a different tolerance level for pain.  After a few minutes, the pain will get better because the area will go numb and you'll be used to the sensation.  Good luck!

Simple: Our skin has sensory nerves =)

No as palm tree is monocotyledonous plant having no cambial or secondary meristemetic activity.Age can be estimated here by leaf scars on trunk.

how do you know that plants don't feel the pain and animals dont have souls?\nthink again.....

Thorns Spines and Prickles have only one thing in common viz. they are all very sharp pointed and helpful as a defense mechanism.\n\n Now let us see the differences ( All Botanical)\n\n1) Spines = these are all modified LEAVES; i.e. the leaves are turned in to or reduced to spines. Very good example is Cactus. In all cacti the stem does the function of photosynthesis (Phylloclade) and the leaves are turned in to spines to reduce the rate of transpiration and also act as defense mechanism against animals.They are seen at the node where a leaf is expected\n\n2) Thorns = These are all modified branches ( i.e. stem modification). They either develop from terminal or axillary buds.. They are also used for defense.They are seen only at the node of the plant.They are endogenous in origin i.e. from the vascular tissue.Examples are Pomegranate, Bougainvillea\n\n3) Prickles = These are NOT modifications of any existing organ of a plant. They are entirely new organs ( "Organa de novo" as said in Latin).They are found any where and indiscriminately on the plant( Stem , leaves ) . They are exogenous in origin ( develop from epidermal tissue only). Therefore they break off easily. Rose is an excellent example.

Pain is a fairly universal defense mechanism of life forms. It is nothing but the message (along neural cells) to the rest of the body (or at least the closest node in the nervous system) that something is wrong, so that the body can react by sending repair and defence agents. \n\nFish are vertebrates, and all vertebrates have a brain which coordinates most of their bodily functions. Mammals aren't that different from fish in this regard. Fish have more different sensory organs than mammals, all of which are coordinated in the brain.\n\nThere are also autonomous neural systems in vertebrate bodies. The intestines are a complex, self-regulating neural system with only little communication with the brain.\n\nIt is perfectly possible to make a fish "drunk" (i.e. reduce coordination of neural activity) by exposing it to chemicals. What levels of alcohol are required for it to act as a neurotoxic substance may differ from air-breathers, since the respiratory organs may be a better conductor for alcohol into the blood than the intestinal organs. Or in other words, think of inhalable alcohol.

Why shouldn't caffeine effect plants?  Plants are living, just like humans, plants have hormones that determines its growth development.  Caffeine effects humans, so why shouldn't it effect plants?  \n\nPlants do not have a nervous system because what do plants do?  They just sit.  Due to this, plant growth and development is strictly based on the secretion of different hormones, which is why it takes them so long to respond to the outer environment.  Although some plants can immediately respond to a brush of a wind (Mimosa pudica), most like household plants move very slowly.  When given a substance like caffeine or steroids, it can have devastating effects.  In a human, caffeine simply goes to a neuron and basically occupies the Ca receptor and stimulates our muscles by keeping the flow of action potentials constant non-stop for a period of time.  A constant consumption of caffeine will result in a dead neuron, you will basically over work the neuron.  In a plant, the caffeine does not have a place to dock.  Instead, it messes up the different hormones or docks in crucial receptors that are needed for growth.  If the receptor is blocked, then the hormones cannot be expressed, causing a change in the growth pattern of the plant.  I mean, if caffeine is able to outcompete our natural signals, then it for sure can knock out a plants signal to grow in the right manner.

Any rooted plant does - you could pick an oak tree or a rose bush, or even a marijuana plant if you wanted.\n\nThe roots grow down, toward the center of gravity. The leaves and stem grow up, away from the center of gravity.

Non-vascular plants do not have vascular systems to carry water, nutrients, ant the products of photosynthesis throughout the plant. Non-vascular plants include mosses, ferns, hornworts, and liverworts. The mosses, hornworts, and liverworts all transport water by osmosis so they cannot grow very large. This is why they must live so close to water. Ferns have a primitive forrunner of a vascular system, but it is not really a real vascular system because they do not have true roots, and also lack xylem, which is a type of cell that carries water and nutrients up the plant, and phloem, which are cells that can carry water, nutrients, and the products of photosythesis throughout the plant. If you have any more questions, I'll check back here for updates if this was helpfull at all.

I would say so from my experience with homeopathic treatments.  I would depend if the pain was superficial or deep muscle pain.  I don't think it would help much with nerve pain, but it works like a charm for muscle pain.

The mosses and liverworts are non-vascular-All the rest are vascular.\n\nhttp://blue.utb.edu/biology/Oliva/notes_plants.htm\n\nhttp://www.saskschools.ca/curr_content/biology20/unit3/unit3_mod6_les1.htm

I have no ever felt pain.  I always thought it was so cool to dream about being stabbed and never feel a thing.  \nI've woken up crying after a sad dream, but never ever felt pain.

Please don't give your plant a vitamin made for a human. The plant is energetically connected to you now. Just from sharing in your space. It would be in your best intrest to take very good care of the plant. It will bring you prosperity.

what kind of plant is it ? some do.

Scientifically speaking, we can't be sure whether mosquitoes, or any other insects for that matter, feel pain. They seem to feel distress when put into a stressful situation, but we can't be sure whether they experience pain in the classic sense. Insects DO have brains and spinal chords, but they do not have a central nervous system like most other animals. We can't be sure whether response to a painful stimulus is a result of experiencing pain, or if it is merely an instinctual, reactionary response. \n\nI like to give ALL animals, including insects, the benefit of the doubt and assume that they DO feel pain, unless we can prove otherwise. But who is to define what pain is for another species?
