Question

The dicot root is identified by the presence of

• A. Endarch xylem
• B. 2-6 radial vascular bundles
• C. > 6 radial vascular bundles
• D. Absence of pith and endodermis

Answer 1

The correct option is B 2-6 radial vascular bundles

Dicot root vascular bundles are described as radial and tetrarch. There are four bundles each of xylem and phloem occurring alternately. Xylem is described as exarch. Endodermis is present in dicot roots. Pith is absent in older dicot roots.
Thus, the correct answer is option B.
