Question

In grass, ligule occurs on

• A. Sheathing leaf base
• B. Leaf blade
• C. Petiole
• D. Between sheathing leaf base and leaf blade

Answer 1

The correct option is D Between sheathing leaf base and leaf blade

A ligule is a thin outgrowth which is found at the junction of sheathing leaf base (leaf base is broad and surrounds the stem as an envelope) and leaf blade. It is commonly a form of a translucent membrane or a fringe of hairs. The ligule appears to be a continuation of the leaf sheath and encircles the stem as done by the leaf sheath.

So, the correct answer is 'Between sheathing leaf base and leaf blade'.
