Question

What type of roots are found in Momordica charantia (bitter gourd)?

• A. Tuberous
• B. Beaded
• C. Stilt
• D. Nodulous

Answer 1

The correct option is B Beaded

Adventitious roots are modified for storage, additional support, nutrition and respiration. They may be tuberous, fasciculated, moniliform, nodulose and annulated. Moniliform or beaded roots are swollen at frequent intervals. This formation gives a beaded or type of appearance. Roots of bitter guard are of this category. Tuberous roots are swollen, irregularly shaped tubers which arise single from each node. For example: Sweet potato.When a slender root is swollen abruptly at the apex, it is said to be nodulose. For example: Mango-ginger. Stilt root is modified root coming from the lower node of stem. For example: Sugarcane.

Thus, the correct answer is option B.
