Question

A bicollateral vascular bundle is characterised by

• A. Phloem being sandwitched between xylem
• B. Transverse splitting of vascular bundle
• C. Longitudinal spitting of vascular bundle
• D. Xylem being sandwiched between phloem

Answer 1

The correct option is D Xylem being sandwiched between phloem

The large xylem vessels in the center are sandwiched between two layers of phloem (bicollateral bundle) that can be identified as groups of smaller cells above and below the xylem. Typical pairs of sieve tubes and smaller companion cells are found only in these parts of the vascular bundle.

So, the correct answer is 'Xylem being sandwitched between phloem.'
