Explanation:

A piece of paper catches fire when a burning matchstick is brought near it. ... When a lighted matchstick is brought near a piece of wood it does not start burning because the ignition temperature of wood is higher than a piece of paper.

Answer 2

Answer:

There are two things to consider. Paper is treated with chemicals that break down part of the cellulose so that it makes paper, not wood, so it isn’t cellular any more, it is fiber, strands of very fine fibers. These compressed fibers are then dried thoroughly, so the result is there is little to impede ignition when a flame is present. Wood almost always contains some water or moisture, which takes time to heat up and evaporate out, and the cells are larger individual parts than strands of fiber.

Some woods, for instance yellow pine, has a terpene rich sap (think turpentine) that is readily ignited, so don’t kid yourself, some woods are extremely flammable, especially dry, resinous woods.
