hilum
seed
Quick Summary
The hilum is a scar on a seed, such as a bean, that marks where the ovule was attached. In flowering plants, seeds develop from ovules found within the ovary. After fertilization, the ovule matures into a seed, and the hilum is a visible mark on the seed's surface indicating its former attachment point. Sometimes, a small opening called the micropyle, which is where the pollen tube entered the ovule, can also be found on the seed coat.123
