Type of flower and pollination that is observed in the given plant is

	Flower 1	Flower 2
1.	Chasmogamous and undergoes self-pollination	Cleistogamous and undergoes cross-pollination
2.	Cleistogamous and undergoes cross pollination	Chasmogamous and undergoes self-pollination
3.	Chasmogamous and undergoes self-pollination	Chasmogamous and undergoes cross-pollination
4.	Chasmogamous and undergoes cross pollination	Cleistogamous and undergoes  self-pollination

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 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-pollen landing on the stigma.
