Question

• A. Numerous scattered
• B. Arranged in a ring
• C. Without cambium
• D. Surrounded by bundle sheath

Answer 1

Answer: (B)

Arranged in a ring

Eustele - In this arrangement, the primary vascular tissue consists of vascular bundles, usually in one or two rings around the pith. In addition to being found in stems, the eustele appears in the roots of monocot flowering plants. The vascular bundles in a eustele can be collateral with the phloem on only one side of the xylem or bicollateral with phloem on both sides of the xylem, as in some Solanaceae.

Thus, the correct answer is option B.
