Answer: In plants, autogamy is the process of self-fertilization. The plant’s pollen is delivered to its own stigma or ovule, where fertilisation takes place. The autogamy fertilisation mechanism has evolved and adapted in many plants. They frequently do not fully open, preventing self-fertilization. In others, the stamens bend and twist inward to fertilise the stigma of the plant. One of the disadvantages of autogamy is that the plant’s progeny often deteriorates with time.
