The buildings collapse from the top and fall straight down. So just no on this point.

I highly doubt the roots of the tree will suddenly just implode on themselves and have the tree fall inwards into the dirt forming a neat pile of tree rubble.

This has already been explained, over and over time and time again by people who are actually engineers and not just message board posters like you and I. In short, the steel didn't have to completely melt, just reach a point where it was no longer capable of holding the weight of the floors above it. As the floors began to collapse, inertia and gravity REQUIRED the buildings to fall down.

There are pictures of not only chunks falling on tower 7, but a huge section of the corner of the building missing .
