After fertilization, the ovule and ovary subsequently develop to form

In angiosperms, fertilization triggers significant developmental changes in the female reproductive organs. Following the fusion of male and female gametes, the zygote develops into an embryo [1]. Simultaneously, the ovules, which are located within the ovary, undergo transformation to become seeds [4]. The ovary itself, which acts as the protective vessel for the ovules, swells and matures into a fruit [4]. This process ensures that the seeds are enclosed within the fruit, which aids in protection and eventual dispersal by various agents like wind, water, or animals [3]. While other floral parts like petals and stamens typically wither and fall off after fertilization, the ovary wall (pericarp) and the ovule's integuments (seed coat) persist to form the final fruit and seed structure respectively [1]. Therefore, the ovule and ovary develop into the seed and fruit respectively.
