After fertilization, the ovary ripens and becomes a fruit. A single grape is a fleshy fruit called a berry. This refers to the fact that the ovary walls have developed into a fleshy pericarp and that the ovary contains at least one carpel containing seeds.

The endocarp, mesocarp, and exocarp collectively make up the pericarp. The mesocarp is made up largely of parenchyma cells. The exocarp forms the epidermis of the berry.

The embryos exhibit axile placentation (Rost, et. al. 200). When fully developed, the embryos will be surrounded by a tough seed coat that has developed from the inner and outer integuments of the ovule.
