  2. Malvaceae

  3. Liliaceae

  4. Poaceae

Lemma is

  1. Superior palea

  2. Inner palea

  3. Both A and B

  4. Inferior or outer palea


Correct Option: D
Explanation:

The spikelet inflorescence is seen in family Poaceae. 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 the 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 is present. Hence, Lemma is the inferior or outer palea.

So, the correct answer is 'Inferior or outer palea'.

  • So, the correct answer is 'Mustard'

A graminaceous spikelet is surrounded by

  1. Two scales called glumes

  2. Two scales called lemma and pale

  3. Two scales called lodicules

  4. None of the above


Correct Option: A
Explanation:

In graminaceous spikelet or spikelet inflorescence of Poaceae, there is a pair of sterile glumes at the base of the spikelet. The lower, outer glume is called the first glume and the upper, inner glume is called the second glume. Just above the glumes, spikelets are present which are partly enclosed by glumes. Spikelets are characteristic of the grass family.

So, the correct answer is 'Two scales called glumes'.
