What type of placentation is there in apple?

In Apples, the type of placentation is known as axile placentation. Axile placentation occurs when the ovules are attached to the central axis or column of the ovary. In the case of Apples, the ovules are attached to the central column within the ovary, which eventually develops into the core of the Apple fruit. This type of placentation is common in fruits of the Rosaceae family, to which Apples belong.
