how many compartments compose the ovary (of a flower) whats located in each compartment?

Answer 1

Ovary is composed of one to several obvious compartments (often called cells, or carpels).
In most wild plants the number of cells in an ovary is fixed. In fact, cell number often helps us identify unknown plants.
Inside each cell of the ovary, several tiny, soft, pale, oval items called ovules develop.
ovary enlarges to become become a fruit, as ovules inside the ovary mature into seeds.
