Is the arrangement of vascular bundles in the stem same for all plant species?Explain

blsea [12.9K]

$\huge\boxed{\fcolorbox{red}{yellow}{Answer:- }}$

No, the arrangement of vascular bundles in the stem same for all plant species.

<h2>☆ <u>In</u><u> </u><u> Monocot </u><u> </u><u>Stems</u></h2>

In monocots, xylem and phloem are organized in vascular bundles scattered throughout the stem. As the plant grows, monocot stems generate new vascular bundles for the new tissue. Monocot stems in general possess a simpler arrangement than that found in dicots.

<h2>☆ <u>In Dicots</u><u> </u><u>Stems</u></h2>

Within the class of plants known as dicots, herbaceous dicots and woody dicots have different arrangements of vascular tissues. In herbaceous dicots (plants, mostly annuals, with soft, non-woody stems), vascular tissue remains in discrete bundles even at maturity. In contrast, when mature woody dicots (plants, mostly perennials, with woody stems) reach maturity, the vascular bundles join together to form continuous rings around the interior of the stem.
