NEET BIOLOGY

Detailed explanation-1: -In woody plants, this process produces wood, and shapes the plant into a tree with a thickened trunk. Because this growth usually ruptures the epidermis of the stem or roots, plants with secondary growth usually also develop a cork cambium.

Detailed explanation-2: -1: Primary and secondary growth: In woody plants, primary growth is followed by secondary growth, which allows the plant stem to increase in thickness or girth. Secondary vascular tissue is added as the plant grows, as well as a cork layer. The bark of a tree extends from the vascular cambium to the epidermis.

Detailed explanation-3: -Secondary tissues are produced in woody plants. Secondary xylem and secondary phloem are produced from a cylinder of meristematic tissue within the woody stems and roots. This cylinder of meristematic tissue is the vascular cambium.

Detailed explanation-4: -Vascular cambium and cork cambium, also called secondary meristem, are responsible for secondary growth in plants. They increase the thickness of the plant body.

Detailed explanation-5: -The secondary growth of plants increase in stem thickness and it is due to the activity of the lateral meristems, which are absent in herbs or herbaceous plants. There are two types of lateral tissues involved in secondary growth, namely, vascular cambium and cork cambium.
