Question

In sugarcane, the adventitious roots are called as

• A. Prop roots
• B. Prop and tuberous roots
• C. Pneumatophores
• D. None of the above

Answer 1

The correct option is D None of the above

Adventitious roots do not arise from the radical of the seed. Instead, they can originate from the plumule parts such as stem, branches, leaves. Hence, they are termed as adventitious roots. In sugarcane, adventitious roots are stilt roots or brace roots. Prop roots are aerial roots that are developed from the horizontal branches of the stem that hang vertically downwards. They provide mechanical support to the plant. Tuberous roots are swollen, irregularly shaped tubers which arise single from each node. Pneumatophore is a type of roots that grow negatively geotropic for taking in oxygen from the air.
