WebbThe reproductive structures, seeds (fertilized ovules) and microsporangia, are produced in cones (strobili). The female or ovulate (seed) cone consists of a spiral series of overlapping ovuliferous scales each producing two ovules on the upper surface.

In flowering plants, the ovule is located inside the portion of the flower called the gynoecium. The ovary of the gynoecium produces one or more ovules and ultimately becomes the fruit wall. Ovules are attached to the placenta in the ovary through a stalk-like structure known as a funiculus (plural, funiculi).
