Question

Choose the correct answers from the alternatives given.
When a leaf trace extends from a vascular bundle in a dicot stem, what would be the arrangement of vascular tissues in the veins of the leaf

• A. Xylem would be on top and the phloem on the bottom
• B. Phloem would be on top and the xylem on the bottom
• C. Xylem would encircle the phloem
• D. Phloem would encircle the xylem

Answer 1

The correct option is A Xylem would be on top and the phloem on the bottom

Vascular bundles are scattered in the spongy parenchyma. These can be seen in the veins and the midrib of the leaves. The dicot leaves possess reticulate venation in which veins form a network. The xylem forms the top layer and phloem is present at the bottom in the arrangement of the vascular tissues. The veins vary in thickness in the reticulate venation.

Hence, the correct answer is 'Xylem would be on top and the phloem on the bottom'.
