Detailed explanation-1: -The vascular cambium is the main meristem in the stem, producing undifferentiated wood cells inwards and bark cells outwards.

Detailed explanation-2: -The lateral meristem tissues are responsible for the secondary growth of plants.

Detailed explanation-3: -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. Figure 3.2.

Detailed explanation-4: -Cambium is the layer of actively dividing cells between xylem and phloem tissues that is responsible for the secondary growth of stems and roots. The cambium produces new layers of phloem on the outside and of xylem on the inside, thus increasing the diameter of the stem.

Detailed explanation-5: -A secondary meristem is a type of meristematic tissue that is responsible for the secondary growth in plants, i.e. growth in girth or thickness. It is opposed to the primary meristem that is involved in the primary growth, i.e. growth in height or length.
