Question

A conjoint vascular bundle is one in which xylem and phloem are

• A. Joined together
• B. Separate
• C. On same radius
• D. On alternate radii.

Answer 1

The correct option is A Joined together

The conjoint vascular bundle is just an arrangement how the vascular bundle i.e. the combination of xylem and phloem is arranged. Here the xylem and phloem are arranged together in the same radius. Conjoint vascular bundles are seen in stem and leaves. They serve the primary purpose as any other vascular bundle for transmitting sugar, nutrients, water etc across the plant. They are divided into three categories i.e. collateral, bi-collateral and concentric vascular bundles. In a conjoint arrangement, the xylem is found in the interior while phloem is towards exterior and called adaxial and abaxial respectively.

So, the correct answer is 'Joined together'.
