Vedclass · Answer

(A) Secondary growth is the increase in the thickness or girth of the plant body.It is primarily caused by the activity of the vascular cambium and the cork cambium.In dicot stems,the vascular cambium is present between the xylem and phloem,which allows for the production of secondary xylem and secondary phloem,leading to secondary growth.Monocot stems lack a vascular cambium,and therefore,they do not exhibit secondary growth.While roots of dicots also undergo secondary growth,the question specifically refers to the standard occurrence in stems,making the dicot stem the most appropriate answer.
