    Mean Plants
Click For Summary
Plants sense light and grow towards it through mechanisms like phototropism and thigmotropism, which involve cellular responses to environmental stimuli. Unlike animals, plants lack a centralized nervous system; instead, their growth direction is regulated by chemical signals and feedback loops among cells. These processes allow plants to respond to light, gravity, and moisture without the need for rapid responses typical of animal nervous systems. The discussion emphasizes that while plants do not have a "brain," their cellular coordination is complex and effective for survival. Understanding these mechanisms helps clarify how plants interact with their environment.

Yes we are made from matter, all matter interacts (energy). The emergent property of the interaction of our brain creates consciousness. The last two sentences of your post do not make sense

look, its just like the phrase, "what came first, the chicken or the egg." but in this case its, "what came first, God or existence. I am disappointed that you all believe that this is my own crackpot theory when its just what iv'e heard and read on the internet. and you can never be 100% sure there's always goin to be a lot more to nature than we think.

Totally agree! It drives me up the wall that people grab at buzzwords like quantum and nano and attach them to their ideologies to make them seem more legitimate when in actual fact they have little or no understanding of the science involved.

If you're sitting down here's a fun quantum link

EDIT: Link removed about Quantum jumping

Everyone has a basic understanding of Quantum physics. i don't see the problem with throwing the word around. no one is trying to be arrogant!

1. Don't believe everything you hear and everything you read - internet has a lot of good but also has a very large collection of crap.

2. There may be more than we think, but that does not mean we can fill in the blanks with fairy tales (as per that brilliant Dara O'Briain quote).

3. Leave god out of it, there's no reason to invoke it in any way, shape or form.

No, hardly anyone understands it. Don't make things up.

The majority of the public haven't got a clue about it.

It is bad to throw the word around because it doesn't mean anything in the incorrect context in which it is being used (by yourself and others).

No one said anyone is being arrogant, just using terms incorrectly.

What does quantum physics have to do with anything. And what do you mean that consciousness creates energy? It makes no sense whatever...

And what do you mean "everything is consciousness"? Consciousness comes to existence through neuron interactions in our brain, it's nothing more than that. And consciousness does not travel "faster than light", like your other posts tells us. It is nonsense...

i was just stating what i have read and seen on the internet. some people see consciousness as a connection to spirituality. Everything being consciousness is a theory from people that believe in a prime creator. with consciousness we are able to minipulate energy, matter and etc.

As above.

Well, let's leave it out. It doesn't belong here. Stick to the mainstream.

Unless you are referring to it in a "it let's us control arm movements" way, that's completely crap.

It may not be your own crackpot theory, but it is a crackpot theory with no scientific basis, and there's no need to repeat it here. The Internet is far from the most accurate of sources. While there is a lot of good information on the Internet, there's an extremely high noise to signal ratio.

Actually very few people fully understand quantum mechanics. In these situations, "quantum" becomes a meaningless buzzword without any scientific significance.

hm well none the less these are topics i need to study on more. but it truly seems that existence is a lot more than just particle and energy connections.

There's evidence for plants utilizing quantum mechanics for photosynthesis:
http://sitemason.vanderbilt.edu/files/iqLVYI/Fleming 2004 Nature 431 256.pdf

The philosophy you're implying is called "panpsychism" and as you can see, it's not a very popular view. But any question of whether other things (animals, plants, weather, rocks) have a subjective experience is not really a biological question at this point. These kinds of discussion take place in the philosophy forums instead.

We have absolutely no idea what's special about our matter/energy configuration that allows us to have subjective experiences. In the philosophy forum, topics like panpsychism come up, but there's also an interest in more tangible approaches, like information theory. You would find more productive answers to your inquiries there (but don't go too fast, quantum consciousness is considered "crackpot" even by most neurophilosophers).

im new to this whole site and i had no idea that there was a philosophy forum. could you locate it for me?

Make sure you read the rules before launching into anything. They were changed recently and made strict to ensure quality posting.

it's a subforum within the "General Discussion" subforum almost at the bottom of the main forum page. So a subsubforum :)

What makes you say that? I really don't see the need for quantum physics to be involved in consciousness anymore than it is involved in any macroscale science

it does because we all hear much about astrology, psychics, spirits and the paranormal including intuition. there must be things in existence that just isn't comprehendable. everything exists for a reason so how and why would people speak on the paranormal.

People like to make things up, especially if it makes them money. That's why people do it, that's the motivation. Oh no, have I spoilt your fantasy that it's all real?

There is zero evidence for the paranormal or anything you list above existing.

Yes, of course we have all heard about it. And if you look it up on the internet, then you would find billions of sites about it. But we've also heard of vampires and werewolves. Do you think those things are real.

There is absolutely NO evidence for paranormal phenomena. So if you think scientifically, then these things do not exist. Fine, believe in it if it makes you happy, but that doesn't make it real.

Why would everything exist for a reason? I've heard a lot of people saying that, but I could never comprehend people saying that. Things exist because they exist, why do there have to be a reason behind everything?
