Options
- ASome plants such as Viola (common pansy), Oxalis, and Commelina produce two types of flowers –chasmogamous flo
- BCleistogamous flowers are invariably autogamous as there is no chance of cross-pollen landing on the stigma
- CCleistogamous flowers produce assured seed-set even in the absence of pollinators.
- DNone of the above
Correct answer
D. None of the above
Step-by-step solution
Autogamy in such flowers requires synchrony in pollen release and stigma receptivity and also, the anthers and the stigma should lie close to each other so that self-pollination can occur. Some plants such as Viola (common pansy), Oxalis, and Commelina produce two types of flowers –chasmogamous flowers which are similar to flowers of other species with exposed anthers and stigma, and cleistogamous flowers which do not open at all (Figure 1.9c). In such flowers, the anthers and stigma lie close to each other. When a
