Question

A narrow layer of thin-walled cells found between phloem$/$ bark and wood of a dicot is?

• A. Cork cambium
• B. Vascular cambium
• C. Endodermis
• D. Pericycle

Answer 1

The correct option is B Vascular cambium

In dicotyledonous stems of temperate trees, during secondary growth, vascular cambial ring(narrow layer of thin-walled cells) produces secondary phloem towards outer side and secondary xylem or wood towards inner side.

So, the correct option is ‘vascular cambium’.
