Which of the following meristem is responsible for wood formation in plants :

Explanation

The meristem responsible for wood formation in plants is the lateral meristem, specifically the vascular cambium and the cork cambium. Lateral meristems are responsible for the secondary growth of plants, which involves the thickening of stems and roots. The vascular cambium is a type of lateral meristem located between the xylem and phloem tissues in the stems and roots of woody plants. It produces new xylem cells towards the center of the stem, contributing to the growth of wood. The cork cambium, another lateral meristem, produces the outer bark of the stem, providing protection to the underlying tissues.
