Question

In a banana, true stem is underground. The stem like structure outside soil is formed by

• A. Peduncle
• B. Petiole of leaves
• C. Leaf bases
• D. Overlapping of leaves

Answer 1

Answer: (C)

Leaf bases

Banana posses a unique shoot system. The true stem is present below the soil as modified stem known as a rhizome. The leaf base known as hyphopodium leads to the production of the thin slender stem-like structure known as suckers above the soil. It grows horizontally in the soil and ultimately comes out to form a new aerial shoot or crown. Each sucker has nodes with scale leaf and axillary bud.

So, the correct answer is option C.
