Question

Peduncle is reduced to a point in which type of Racemose Inflorescence?

• A. Umbel
• B. Corymb
• C. Spikelet
• D. Spike

Answer 1

The correct option is A

Umbel

The correct option is A:

Explanation for Correct option:

1. An Umbel is a type of inflorescence in botany that consists of a number of short flower stalks (called pedicels) that extend out from a central point, like umbrella ribs.
2. The corymb and umbel are two different varieties of shortened-axis racemose inflorescences in which the main axis grows indefinitely and ends in a flower.

Explanation for Incorrect options:

Option B:

1. Corymb is a botanical word describing an inflorescence in which the outermost blooms are carried on longer pedicels than the innermost, bringing all flowers up to the same level.

Option C:

1. A spikelet inflorescence is an elongated main-axis inflorescence that is also a racemose inflorescence.
2. Spikelets can be found in grasses.
3. Individual floral units are used to represent spikelets.

Option D:

1. A spike is a raceme, but unlike barley, the flowers emerge directly from the stem rather than on pedicels (Hordeum).
2. The flowers of a spike are attached directly to the axis at the axil of each leaf, rather than to a pedicel, as they are in a raceme.

Final answer: Peduncle is reduced to a point in which type of Racemose Inflorescence Umbel.
