Answer:
What can you catch but not throw?
I am a fruit with seed on the outside.
I am long and slim works in light. Has but one eye and an awful bite.
In prison I'll be found. But I would never go to court Unless there's more than one
I have roots nobody sees. I am taller than trees. Up up I go but I never grow.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
