Summary

[edit]
Description

cross section: Zea stem magnification: 100x

<a href="http://blogs.berkshirecc.edu/bccoer" rel="nofollow">Berkshire Community College Bioscience Image Library</a>

The vascular bundles in the roots and stems of monocots are typically closed, meaning the xylem and phloem are adjacent to each other. There is no vascular cambium, limiting the possibility of secondary growth. The vascular tissues are often wrapped in a bundle sheath of starch containing parenchyma or, in the case of Zea, supportive, heavy walled sclerenchyma.

The vascular bundles in the stem of the monocot Zea are both closed and collateral, meaning xylem and phloem are adjacent to each other and occupy the same radii on the stem axis. Cambium is lacking so no secondary growth is possible.
