Question

why does certain plants grow in girth while others don't? think of the timber industry in the absence of lateral meristem.​

Answer 1

Answer:

Girth of the stem increases due to lateral meristematic tissues. They are found beneath the bark (called cork cambium) and in vascular bundles of dicot roots and stems (called vascular cambium) as thin layers. This increase in the diameter and girth of the plant is called secondary growth.
