Answer:
⭐ POLLINATION
✍️ Pollination is the process, which plants depend on to transfer pollen grains from anther to stigma or pistil. It can be either cross-pollination or self-pollination. Most of the plants are bisexual or hermaphrodite

⭐ Pollen-pistil interaction
✍️ The sequence of events, which is carried out from the time of pollen deposition over the stigma and till the entry of pollen tube inside the ovule is called pollen pistil interaction. The pollination, process of transferring pollen grains from the anther to the stigma of the same flower or from one flower to the different flower is the initial stage or the first step in pollen pistil interaction.
️️
All pollinations do not lead to successful fertilization because for successful fertilization, the pistil of a flower has to recognize the pollen of the same species. Therefore, the interaction between pollen grains and the stigma needs to be understood properly. Once compatible pollen is accepted by pistil, events for fertilization proceed, whereas incompatible pollens are rejected. This interaction where a pistil is capable of recognizing its pollen is the result of long term pollen-pistil interaction and chemicals released by pollen.
