It's scientifically known that plants respond to stimuli such as being injured, namely to communicate that fact to others of its species in the vicinity.
For an example I'm sure most people can relate to, you probably know that "cut grass smell" when you mow your lawn? That's the grass throwing out chemical signals telling other grass "Hey! Something cut me down! Be warned!".
While whether this can count as intelligence or sentience is worthy of further debate, to say that trees don't feel anything is a gross mistake.
All living things respond to stimuli, even some non-living things respond to stimuli (like viruses or crystals) so I don't see "response to stimuli" as sufficient evidence that plants suffer pain.
Actually, I'm not categorically opposed to the notion, but I think you need to bring a lot to the table to explain why things without nervous systems feel pain. If the default assumption is that all complex systems feel pain then I wonder if you think things like jetstreams, economies and the internet feels pain.

Note that I didn't say they feel pain, just that they can feel what is done to them by the environment around them and respond appropriately.
The fact trees don't speak human plays a big role in us not understanding them, but they do clearly feel and express things whatever they may be.
>So is it immoral to cut grass?
Considering most of it is done for purely aesthetic purposes to satisfy human egos, arguably yes.
Note that whether it's moral or not is tangent to whether it can be done or not. We humans do plenty of immoral things without a care in the world.
Well, I never said "they feel nothing", but if you're saying plants have a right to life because they feel "something" I'm wondering where you draw the line. If you're something of a panpsychist I'm actually ok with these conclusions in terms of metaphysical consistency.
