Botany - Anatomy of Flowering Plants Question with Solution | TestHub

Growth in the plant is of two types i.e.primary and secondary growth. Primary growth mainly occurs in the primary meristem. They help in increasing the length of the plant because they present on the axis of it. On the lateral side of it, axillary buds are present that form branches. Secondary meristem is of two types i.e. vascular cambium and cork cambium. Vascular cambium is present in between vascular tissue that helps in the secondary growth of the plants and increases the girth of the plants by the addition of cells in the lateral direction. Similarly, cork cambium also helps in the addition of cells in the cortex. So the correct answer is$\mathrm{B}$.
