Venus fly trap..is it a?!
for i notice here that there is a big argument that plants have no feelings and sense no pain..yet the Venus fly trap has a nervous system so it's the argument flawed

No, that's like saying plants can think because the shoots always grow towards light and the roots always grow away from it. These are environmental triggers acting on specialised cell systems on local scales. The rest of the plant does not know when a VFT catches a fly, as there are no signal molecules or electrical impulses travelling off to inform the brain they don't have. This is why we talk about animals having a CENTRAL NERVOUS SYSTEM, not just the capacity to respond to environmental stimuli.
In terms of evolution there is absolutely no benefit to plants experiencing pain because they are unable to move. All animals are mobile for at least part of the life cycle. Pain informs us that damage is occurring to tissues so we can do something about it. Plants can't do anything about it so there is no reason that they would or should feel pain.
So don't confuse a response with a system, vertebrate nervous systems are the most complex thing ever known to exist in the universe. The signalling in plants is vastly more rudimentary, in fact IIRC there are only five hormones in all flowering plants, but there are more than double that number just involved in the reproductive systems of mammals.

I'm no botanist but I'd say the Venus fly trap has no nervous system but it does have a very clever and well evolved capture and feed mechanism! There is a plant in austrailia called sensitive weed and when you touch it all the fronds close up to protect it it's not sentient it's a survival mechanism!
plants, all plants, have nervous systems; they are simply a different structure than those in mammals.
why we are so species-centric, i don't know.

It doesn't have a nervous system, it has reactive triggers. There's no cognition or even the most rudimentary decision-making - when enough of the hair triggers are fired, the gape closes. It's definitely 100% plant.
A slightly more complex nervous system than sunflowers turning to face the sun. Just a mechanical reflex, not really a 'nervous system' as such.
yeah it is a plant
