Because it is still "Green", or as you'd call it still wet,you can still burn it, but it will take an extreamly long time to get it to start , then it will not burn correctly and will smoke and not burn through.

Wood freshly broken or taken from a living tree will be green, that is full of the sap of the living tree and will not readily burn. It will tend to be smoky and will not remain alight unless there is a fair amount of more combustible material surrounding it. Even if quite a bright fire was burning the new wood would probably not completely burnt and turned to ash. In order to make wood suitable for burning it would be necessary to collect dead branches or to store sap wood for some months to dry it out.

HI !
It is very difficult to burn a piece of wood from a freshly cut tree because the wood still contain the nutrients and water which does not allow fire to attack. In other words you have to let the piece of wood dry and then you are able to burn it.

Combustion is a process that requires
1. Fuel
2. Oxygen
3. Activation energy (ignition)
The activation energy required to burn a piece of fresh wood is significantly higher than that of dry wood, as a lot of energy is required to first evaporate the water content.
Hence the difficulty in burning.
A fresh wood would burn say after 15 minutes of putting in the fire as compared to one minute it takes for dry wood to start burning

Because the wood is still wet. Wood needs to be completely dry to get the best burn out of it.

the way a tree is built on a cellular level is the reason why you can't immediately burn it. there are millions of cells that run up the tree that are used to move water and feed the tree keep the wood saturated. that is why you need to burn wood that is dead or has layed out and dried.

wood fresh from a tree has still been absorbing water and nurtients from the ground, causing it to be alive. the wood needs usually several months to completely dry out. burning damp wood is never an easy task.

Because a piece of wood taken from a tree is still full of natural sap and will therefore be wet. If you tried to burn it, you would just produce lots of thick smoke

If the wood is fresh it still contains a lot of moisture so it is difficult to burn. Dead wood has no moisture and will burn easily.

Because it is full of moisture and moisture doesn't burn, old tree wood has had a chance to dry out therefore will burn easier.

Because the "fresh" wood has a lot of moisture. Notice that kindling is usually dried wood.
