Detailed explanation-1: -Pollination occurs in the same flower of a plant is called Autogamy. It is also a type of self-pollination. Xenogamy and Allogamy are the same things and type of cross-pollination in which pollen grains from the flower of one plant transfer to the stigma of the flower of another plant.

Detailed explanation-2: -Pollination can occur within a single flower (self-fertilization), or pollen can land on a different flower on the same or a different plant. About 96% of flowering plant species produce male and female gametophytes on the same plant.

Detailed explanation-3: -Final Answer: The correct statement about pollination is “Cleistogamous flowers are always autogamous”.

Detailed explanation-4: -False. Self-pollination can occur in bisexual flowers, i.e. in flowers having both male and female organs, or it can occur in unisexual flowers where both male and female flowers are borne on the same plant.
