Question

How would a biologist classify the plant stem shown?

Answer 1

For plants, it would be the dicot stem however if I’m wrong let me know ;)

Answer 2

Answer:

The correct answer is option B- Dicot stem.

Explanation:

The vascular tissues in the dicot stem are present in the ring form with pith concentrated at the centre of the stem with xylem and phloem separated by the vascular cambium. This type of arrangement with xylem, phloem, pith with no leaf gaps is known as "eustele" which is a characteristic feature of dicot stem.

Since the given diagram shows the ring arrangement of vascular bundles,  therefore, the correct answer is option B.

In the dicot stem, the vascular bundles are arranged in a ring, with pith concentrated at the core of the stem, rather than being scattered throughout the plant interior. In each vascular bundle, the xylem and phloem are separated by a substance called vascular cambium.
