Question

One of them is absent in closed vascular bundles.

• A. Cambium
• B. Pith
• C. Ground tissue
• D. All of the above

Answer 1

The correct option is A Cambium

Closed vascular bundles have no cambium in between xylem and phloem. They lack cambium hence, unable to grow laterally. Interfascicular cambium is absent in closed vascular bundle. There is direct contact between phloem and xylem. Secondary xylem and phloem are not formed. This is seen in leaves and monocot stems. They are present in monocot stems.

Thus, the correct answer is option A.
