Question

When lenticels are blocked which one dies first?

• A. Root
• B. Shoot tip
• C. Leaves
• D. None of these

Answer 1

The correct option is A Root

• The lenticels are type of cells that are found in the bark of some stems and on the breathing roots (pneumatophores) of mangrove plants.
• Its main function is to form a gateway for the direct exchange of gases between the root cells and the atmosphere.
• So, when these are blocked, the roots will be not able to exchange gases which gradually leads to the death of the root cells and ultimately whole plant dies.

So, the correct option is A.
