Question

Closed vascular bundles are the ones which

• A. Contain cambium
• B. Lack cambium
• C. Lack xylem
• D. Possess lysigenous cavity

Answer 1

The correct option is B Lack cambium

In monocots, the vascular bundles are collateral, conjoint and closed type which means the xylem is located in the inner side while phloem is present outside and xylem and phloem are arranged side by side in the same radius which are not separated by the cambium. Cambium is absent in monocot vascular bundles.

So the correct option is "Lack cambium".
