Explanation:
Detailed explanation-1: -Vascular cambium is a layer of meristematic tissue that produces secondary xylem to the inside and phloem to the outside. This is the reason why woody plants can grow in diameter.
Detailed explanation-2: -The vascular cambium is responsible for the secondary growth in a plant, which involves lateral growth. It increases the diameter of the stem by producing cells that accumulate to form the secondary xylem and phloem. It also forms the outer woody tissue and some of the bark, further increasing the stem diameter.
Detailed explanation-3: -Answer and Explanation: The vascular cambium produces xylem and phloem cells as part of the secondary growth of a plant.
