Vedclass · Answer

(C) In the development of primary xylem,the first-formed xylem elements are called protoxylem. During the early stages of plant growth,when the root or stem undergoes $elongation$,the conducting elements of the protoxylem,which have annular and spiral thickenings,are formed. These types of thickenings allow the xylem vessels to stretch as the organ grows in length. As the organ matures and stops elongating,metaxylem with more complex thickenings (like pitted or reticulate) develops.

When the root or stem undergoes .....,the conducting elements with annular and spiral thickenings usually develop in the protoxylem.
