Question

Bicollateral vascular bundles have tissue arrangement.

• A. Outer phloem - Outer cambium - Middle xylem - cambium - Inner phloem
• B. Outer phloem - xylem - Outer cambium - Inner xylem
• C. Outer phloem - Outer xylem - Middle cambium
• D. Outer cambium - Outer phloem - Middle xylem - Inner phloem - Inner cambium

Answer 1

The correct option is A Outer phloem - Outer cambium - Middle xylem - cambium - Inner phloem

A) Outer phloem - Outer cambium - Middle xylem - cambium - Inner phloem

The vascular bundle having the phloem and cambium strands on both the outer and inner sides of the xylem is called bicollateral. This arrangement is in the sequence of outer phloem, outer cambium, xylem, inner cambium, and inner phloem e.g., cucurbita.
