Solution
The compatibility of the pollen-pistil interaction is determined by special proteins.
Explanation:
The compatibility of the pollen-pistil interaction is determined by special proteins that enable the pistil to recognize compatible pollen, promoting pollen germination and pollen tube growth. If the pollen is incompatible, the pistil prevents its germination or inhibits pollen tube growth, thus ensuring selective fertilization. This dynamic process of recognition and response is crucial for successful fertilization in flowering plants.
