Within the carpels are ovules which develop into seeds after fertilization. In angiosperms, the sporangia are located in the stamen anthers (microsporangia) and ovules (megasporangia). Ovary is superior and has only one carpel with numerous ovules. The lower part of the pistil, where the ovules are produced, is called the ovary. In flowering plants, placentation is the attachment of ovules inside the ovary. Ovary usually has two ovules per locule, side by side. The ovary contains two and more ovules or seedbuds. Styles are simple, with the ovary superior and containing many ovules. The ovary is one-celled, the style two-lobed, and the ovules numerous. Each carpel will usually have a distinct line of placentation where the ovules are attached. It contains bracts and megasporophylls, each of which contains two ovules, arranged in a spiral. In gymnosperms, the ovules or seeds are not further enclosed. The female cone develops two ovules, each of which contains haploid megaspores. Each time pollination succeeds, thousands of ovules can be fertilized. The fertilized ovules produce seeds that are the next generation.
