It depends on how badly the tree is burned. If the xylem, phloem are destroyed, the tree will die. The xylem carries water to the tops of the tree and phloem carries food, the product of photosynthesis, to other parts of the tree from the leaves. If these are destroyed the tree can't recover. If the fire just burned the bark black it could recover. Some trees can send up new shoots from the roots and start over, but most will regenerate through seeds.

I can't entirely agree with Chilli Pepper. Beneath the bark of a tree there is a thin layer of cells called the cambium. This produces the tissues called xylem (which carry water up from roots) and phloem (which carries photosynthetic products from leaves).
The xylem is produced on the inner side of the cambium and forms what we recognise as wood. Each year's production of xylem is one 'ring' of growth, visible when the trunk is cut.
The phloem is a much thinner layer, laid down on the outer side of the cambium, and is much more vulnerable to damage. If, for instance, deer or rabbits chew off the bark in a ring all the way around the trunk, the tree will die. SImilarly, if a tree sustains fire damage around the entire circumference, it will likely die. If some cambium remains intact, it may well survive.
The xylem is not so delicate however. Trees sustain major damage due to fungal and bacterial infections, leading them to develop cavities - we've all seen hollow trees. Search the web for work by Dr Alex Shigo - Compartmentalisation of Decay in Trees (or CODIT) - and work by Dr Klaus Mathek showing that hollow cylinders are as strong as solid ones. Thus the loss of a great deal of internal tissue (from morons setting a fire inside a hollow tree for example) will not necessarily lead to the loss of the tree.

depends what type of Tree some have a fireproof bark and need fire to germinate there seeds which do not start to grew unless there has been a fire to clear away the under growth I believe most of the pines if badly burnt die A tree hit by lighting tend to die as the tree will explode when the sap is super heated into steam. So some will die offers need fire but if a tree is burnt down to the ground I think it is dead

It actually beneficial for burns to happen because it feeds the plant with nutrients and the grass that is burnt doesn't compete with the trees for limited resources

In some ecosystems, trees survive. The short vegetation burns, leaving the trees. Other organisms thrive after the fire.

Nature is a wonderful thing, if the tree is not burnt right through , then possibly - just possibly , life will return again

If it is not too old or young deep rooted tree there is every chance that it will regenerate.After severe forest fires many tree survives and there is every possibilities of regeneration.

if the roots don't get burned then there's hope

Over millions of years it will become a fuel resource.

No, but others still grow if it is still standing and some parts could still regenerate
