elongating

Vedclass · Answer

(A) In the development of xylem, the protoxylem elements are formed first. When the roots or stems are $elongating$, the primary xylem vessels develop annular (ring-like) or spiral (helical) thickenings. These types of thickenings allow the vessels to stretch as the organ grows in length. Once the organ stops elongating, the later-formed metaxylem develops more complex thickenings like scalariform, reticulate, or pitted patterns.

When roots or stems are $..........$, annular and spiral thickenings develop in the protoxylem vessels.
