Ovule development:
Ovule development involves the same basic processes necessary for the formation of other plant organs, such as primordium initiation and specification, directed cell division and expansion, and asymmetric growth and differentiation.
However, ovules differ from other plant structures in their reproductive function and apparent evolutionary origin from sporangiophores (Herr, 1995), allowing the basic developmental processes to be studied in a unique context.
