Voiceless yet cries, wingless yet flutters, toothless yet bites, mouthless yet mutters. What is it?

I have a tree like structure, but I do not have a wooden stump like a tree. I am often seen in the plate of a crying baby .

I end in table but don't have legs, I am a physical object that can be eaten, what am I?

I am easy to lift. Try to throw me far, and you will have a fit. With others like me, I help in flight. By myself I don't have much might.

I have many eyes but cannot see, I grow in the dark, or I turn green When I fell ill, a nation faced woe, What am I
