Ever wondered how a flower "decides" which pollen to accept? Plants have a fascinating way of ensuring that only the right pollen reaches the ovule, and it all starts with pollen-pistil interaction! In this video, we’ll explore why this process is so important and what happens after the interaction. You’ll see how the pollen tube navigates through the ovary, and reaches the ovule. Plus, we’ll uncover how this knowledge is used in agriculture and plant breeding.
