Answer» Correct Answer - D `**` 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. `**` In such flowers, the anthers and stigma lie close to each other. When anther dehisce in the flower bud, pollen grains come in contact with stigma to effect pollination. `**` Cleistogamous flowers are invariable autogamous as there is no chance of cross-pollen landing on the stigma. `**` Cleistogamous flowers produce assured seed-set even in absence of pollinators. |
