The shape of the ovules as they develop often affects the final shape of the seeds. Plants generally produce ovules of four shapes: the most common shape is calledanatropous, with a curved shape.Orthotropousovules are straight with all the parts of the ovule lined up in a long row producing an uncurved seed. Campylotropous ovules have a curved megagametophyte often giving the seed a tight "C" shape. The last ovule shape is calledamphitropous, where the ovule is partly inverted and turned back 90 degrees on its stalk (the funicle orfuniculus).
