उत्तर
Cleistogamous flowers always exhibit autogamy.
Explanation:
Cleistogamous flowers never open, so pollen from other plants cannot reach their stigma. This means they are always pollinated by their pollen, ensuring self-pollination (autogamy). This mechanism does not rely on external pollinating agents, making autogamy guaranteed in cleistogamous flowers.
