Question

which meristematic tissues increases the thickness of root and stem?​

Answer 1

Answer:

Apical meristems give rise to the primary plant body and are responsible for the extension of the roots and shoots. Lateral meristems are known as secondary meristems because they are responsible for secondary growth, or increase in stem girth and thickness.

Answer 2

Answer:

The meristem that helps in increasing girth is lateral meristem. The lateral meristem is responsible for lateral growth of the plant i.e., growth in thickness e.g., cambium and cork cambium.
