Vedclass · Answer

(A) Cleistogamous flowers are flowers that do not open at all. In such flowers,the anthers and stigma lie close to each other. When anthers dehisce in the flower buds,pollen grains come in contact with the stigma to effect pollination. Thus,cleistogamous flowers are invariably autogamous as there is no chance of cross-pollination. This condition is commonly observed in plants like $Commelina$,$Viola$ (common pansy),and $Oxalis$. Among the given options,$Commelina$ belongs to the family $Commelinaceae$,but in the context of standard botanical questions regarding floral morphology and pollination types,$Commelina$ is often associated with the study of cleistogamy. However,if we look at the provided options,$Commelina$ is not listed,but $Commelina$ is a classic example. Re-evaluating the question context,$Commelina$ is the correct answer. Since the options provided are family names,and $Commelina$ belongs to $Commelinaceae$,the question might be slightly misaligned with the options. However,$Commelina$ is the standard answer for cleistogamy.
