Ovule Components

The micropyle is the minute pore through which pollination occurs.
The chalaza is the basal swollen part of the ovule.
Integuments are the outer layers that envelop the mass of parenchymatous tissues in a mature typical ovule.
The purpose of integuments is to protect the ovule and facilitate fertilization.
