My question is simple and straight forward - how does a 1-dimensional string "convert" to a zero-dimensional point particle?

And another one - for the purposes of physics, energy is not a physical object but an abstract mathematical construct. So how can a string of energy have a definite physical size(although it's the lowest tolerated by mathematical physics size - the Planck length)?

Oops, here's another one - How on earth can a 1-dimensional string vibrate without employing a 2nd dimension? The drawings of this alleged physical object I've seen, all portray a 2-dimensional string(string is curved).

What am I missing?
