Question

Even in absence of pollinating agents seed-setting is assured in

• A. Salvia
• B. Fig
• C. Commelina
• D. Zostera

Answer 1

The correct option is C Commelina

A. Salvia is pollinated by insects by the turn pipe mechanism.

B. Fig is pollinated by a wasp. The wasp lays egg in the fig fruits and in turn fig is pollinated.

C. Commelina is a cleistogamous flower which never opens. The pollen from anther lobe fall on the stigma of the same flower and thus, pollination is not dependent on any external agency i.e. pollinators.

D. Zostera is a marine grass which is pollinated inside water.

Hence, seed setting is assured even in the absence of pollinating agents in Commelina.

So, the correct answer is 'Commelina'.
