What is cambium in a tree?
Quick Answer
Cambium is a thin layer of actively dividing cells in a tree. It produces new wood and new bark, letting the trunk and branches grow wider.
The Full Story
The vascular cambium is a growth layer between the wood and the inner bark. It generates xylem cells inward, which become wood, and phloem cells outward, which help transport sugars. This lateral growth is what increases the diameter of stems and roots in woody plants. Damage to the cambium can seriously affect a tree because it is essential to forming new transport tissues.
Key Facts
1.It produces xylem inward and phloem outward
2.It is responsible for a tree's increase in diameter
3.Damage to cambium can harm transport of water and sugars
