Taking a crossection of a tree trunk, since trees grow progressively in concentic rings added to the outside, that part of the wood nearest the centre is the oldest. It is close grained and, because it is in the middle, is called heart wood.
The sap wood is the outer, newer layers which are of more open grain and softer.
Heart is older inner wood.
outer part from heart wood to outer rings is called sap wood and it is very soft not as much stronger
outer part from heart wood to outer rings is called sap wood and it is very soft not as much stronger
Heartwood is wood that has died & become more resistant to decay as a result of deposition of chemical substances.
Sap

Wood is obtained from trees known as exogens. They grow larger by addiing a new layer each year under the outer surface of bark. The centre of the tree is known as the pith and the wood near the pith termed heart wood and is hard and close grained The sap wood is made up of he outer layers and are soft and generally have a more open grain.
ٍSap comes from the stem of the maple tree.Maples are important as source of syrup and wood. Dried wood is often used for the smoking of food.The Sugar maple is tapped for sap, which is then boiled to produce maple syrup or made into maple sugar or maple taffy.
