The xylem is a complex tissue.
There are two types of sclerenhyma conducting cells in the xylem, the tracheids and vessel elements.
Xylem conducts water and minerals from the roots to the top of the plant. It also mechanically supports the plant.
Water moves from roots to stems and then to leaves.
Most absorbed water is lost to evaporation through stomata in leaves.
Evaporation of water from plant parts is called transpiration. Transpiration creates negative tensions in the xylem.
Tensions extend downward from leaves to roots.
Hydrogen-bonded water molecules are pulled upward through the xylem as continuous columns.
Heartwood is dead xylem. On the other hand, sapwood is live, working xylem.
The heartwood, or dead xylem, is very important to the tree. It's what gives the tree support and strength!
So, wood is made up of xylem.
But, what is xylem made of?
