Summary
[edit]DescriptionMonocot Root Vascular Bundles in Zea Prop Root (35240146803).jpg |
Cross section: Zea prop root common name: Corn Magnification: 400x <a href="http://blogs.berkshirecc.edu/bccoer" rel="nofollow">Berkshire Community College Bioscience Image Library</a> The vascular bundles are radially arranged with short arms of xylem interspaced with patches of phloem and parenchymous conjunctive tissue. The xylem is exarch: meaning the older smaller protoxylem is found towards the periphery and younger larger metaxylem to the center of the stem. Phloem tissues of sieve tubes, companion cells and phloem parenchyma are also exarch. The older protophloem is found towards the periphery and the younger metaphloem towards the center of the stem. Phloem parenchyma may become sclerenchymized in older roots. Vascular cambium is absent, preventing secondary growth of the root. |
