Cambium (noun)

A thin layer of actively dividing cells between the xylem and phloem in plants, responsible for secondary growth and the production of new tissues.

Origin:

From latin cambium, from gaulish *cambiō, possibly of celtic origin.

Examples:

1. The cambium is a crucial part of a plant's growth and development.
2. The cambium is located in the stem and root of a plant.
3. The cambium produces new xylem cells that transport water and minerals, and new phloem cells that transport sugars.
4. Without a functioning cambium, a plant would not be able to increase in diameter.
5. Some trees have a thicker cambium layer than others, which contributes to their ability to grow more quickly.
