1. Ovary: This is the base of the flower where the ovules (potential seeds) are located. After pollination and fertilization, the ovary develops into the fruit, which is the structure that protects and houses the seeds.
2. Ovules: These are the structures inside the ovary that contain the female gametes (eggs). After fertilization, they develop into seeds, which contain the embryo of the new plant.
3. Petals: While not directly housing the seeds, petals are important for attracting pollinators, which are necessary for fertilization and seed development.
So, the flower doesn't "make" things specifically for housing seeds. It uses pre-existing structures within itself that transform and develop into fruit and seeds after fertilization.
