Question:

Select the mismatched pair out of the following: Rhizome - Dryopteris, Nelumbo nucifera; Sucker - Curcuma domestica, Zingiber officinale; Tuber - Helianthus tuberosus, Solanum tuberosum; Corm -Crocus sativus, Amorphophallus

Rhizome - Dryopteris, Nelumbo nucifera

Corm -Crocus sativus, Amorphophallus

Sucker - Curcuma domestica, Zingiber officinale

Tuber - Helianthus tuberosus, Solanum tuberosum

Solution:

Sucker is an adaptation in which the stems arise from the underground, grow horizontally and promote asexual reproduction at a neighbouring site. At the new site, it will give rise to a new aerial shoot or crown. The process is repeated. Each sucker has one or more nodes with scale leaves and axillary buds, e.g., Chrysanthemum. Curcuma domestica and Zingiber officinale are the examples of rhizomes and hence the correct answer is option C.
