Question

Choose the correct answer from the alternatives given.
Root nodules are formed from the cells of:

• A. epidermis
• B. cortex
• C. vascular cylinder
• D. pith

Answer 1

The correct option is B cortex

The bacteria enter the developing nodule through a structure called an infection thread, which grows through the root hair into the basal part of the epidermal cell, and onwards into the root cortex.

So the correct answer is "cortex".
