Question

Identify the vascular bundle types with the given diagram

• A. A- Radial, B- Collateral Closed, C- Collateral Open, D- Bicollateral
• B. A- Collateral Closed, B- Radial, C- Collateral Open, D- Bicollateral
• C. A- Collateral Open, B- Bicollateral, C- Collateral Closed, D- Radial
• D. A- Collateral Closed, B- Bicollateral, C- Collateral Open, D- Radial

Answer 1

The correct option is D

A- Collateral Closed, B- Bicollateral, C- Collateral Open, D- Radial

The absence of cambium makes figure A - Closed Collateral, while the presence of cambium makes C - Open Collateral. Figure B has phloem between two xylem vessels, making it bicollateral. In the last figure, you can see radial arrangement of vascular bundles.
