Question

An awn or arista when present occurs over

• A. Pale
• B. Lemma
• C. Glume
• D. Lodicule

Answer 1

The correct option is B Lemma

An awn is the fibrils found on grains and arista is the bristles or similar bristle-like appendages on barley, oats, grasses etc. The spikelet consists of a short axis called rachilla on which 1 to many sessile or short-stalked flowers are borne. The florets may be arranged in an alternate or opposite manner on the central axis. At the base of rachilla two sterile scales, called glumes, are present. Above the glumes a series of florets are present. Each floret has an inferior palea or lemma and above it a superior palea. The lemma frequently bears a long, stiff hair called awn.

So, the correct answer is 'Lemma'.
