Vedclass · Answer

(A) In a mature dicot stem undergoing secondary growth, the arrangement of tissues from the periphery (outside) to the center (inside) is as follows:$1$. Phellem (Cork) - The outermost protective layer formed by the cork cambium.$2$. Secondary cortex (Phelloderm) - Formed by the cork cambium towards the inside.$3$. Secondary phloem - Formed by the vascular cambium towards the outside.$4$. Wood (Secondary xylem) - Formed by the vascular cambium towards the inside.Therefore, the correct sequence from outside to inside is: Phellem $(d) \rightarrow$ Secondary cortex $(a) \rightarrow$ Secondary phloem $(c) \rightarrow$ Wood $(b)$.Thus, the correct order is $(d), (a), (c), (b)$.

Read the components $a$ to $d$ given in the note and identify the correct sequence of components from the outside to the inside of a mature stem:
$(a)$ Secondary cortex
$(b)$ Wood (Secondary xylem)
$(c)$ Secondary phloem
$(d)$ Phellem (Cork)
