What is the difference between a nut & a seed? & what is a coconut?

[KatyMac]

Please I'm sure there is a real difference

It can't be that complicated

Is it?

That could be usful to know

Does a nut have an inedible shell and a seed an edible one?
Actually that theory has holes all over it esp in light of TMMJ friends story.
A coconut might be a clue but then again...?

So nuts are tree seeds
& seeds are plant seeds

I think

So a coconut is a nut

Well one of the children asked me & I didn't know

I don't like not knowing stuff so I ask

Sorry it's much less exciting

Mind you we have to refuse children with nut allergies to childminding - cos we have a fifty ft Walnut Tree in the garden
