Hilum

Explanation:

The placenta is attached to the developing seed near the Hilum. The hilum is a scar on the

seed coat through which the developing seeds were attached to the fruit.

Above the hilum is a small pore called the micropyle.

The outer layer of the seed coat is called testa.

Chalaza is a tissue where nucellus and integument are joined. Nutrients from the plant travel through vascular tissue in the funiculus and outer integuments through the chalaza into the nucellus.
