Functions mentions below
Explanation:
Funicle, micropyle, integuments, nucellus, embryo sac, hilum, chalaza, and other components make up an ovule.
Funicle - The funicle is the stalk of the ovule that connects it to the placenta. Short and multicellular funicle.
Hilum - The place where the funicle links the ovule's main body.
The layers that surround the ovule are known as integuments. There are two types of integument: exterior and inner. The primary purpose of integuments is to protect the internal organs.
Micropyle - Micropyle refers to the opening on the top of the integuments. The major purpose of the micropyle is to allow pollen tubes to enter the ovule.
Chalaza is the inflated portion of the ovule that is found opposite the micropyle.
The embryo sac is located in the nucellus and contains a female gamete known as the egg.
