I would argue that plants are clearly different from animals.
At the same time, we share obvious similarities. We are both alive. We both endeavor to survive, thrive, and reproduce. We both respond to stimuli in our environments. We happen to share many of the same compounds in our bodies. To say we are "different" or "no different" depends on where you choose to draw the line.
How do you know plants have feelings?
Do vegetables and fruits try to avoid you when you pick them up from plants?
Let's turn those questions around.
How do you know plants don't have feelings? The first question you may want to ask is "Can I communicate with plants?" Can anyone? Not well, I imagine.
It's worth pointing out that we can't communicate effectively at all with many animals (like invertebrates and fish), yet many people will still try to afford some courtesy to them. Most considerate people I know wouldn't even swat a fly without a good reason. Or cut down a tree. Or pull up a flower bed.
As for plants not running away, well, do plants jump into your mouth? Do they chew themselves?
Plants do move, by the way. Most don't move very much. Only enough to reach sunlight or water and so slowly that many people wouldn't realize it unless you were paying attention. Instead of rapid movement, most plants have evolved toxins, poisons, barbs, tough skin, and other passive defenses to avoid or limit predation (gee, sounds like another Kingdom I know!). In turn, animals have evolved processes to neutralize toxins or safely bypass these defenses. Like a tough beak to break a shell. Or a stone mill to grind a seed (that's us, by the way).
Fruit seeds are actually quite digestible after you grind them up. Toxins and all.
Another thing is eating seeds and nuts.But you can compare seeds and nuts with sperm, usualy men waste a lot of it just for pleasure and only a very small amount is really used for reproduction.
Not a fair comparison, actually. Sperm is one thing. So is an unfertilized egg. Separately, neither of these can reproduce life (not as many of us are familiar with it, anyway). Seeds are closer to fertilized eggs. They contain everything necessary to begin growing into a new plant.
In animal terms, grinding up something like, say, a staff of wheat is a lot like murdering the mom with her baby. Food for thought.
