Integuments encircle the nucellus except at the tip where there is a small opening called micropyle.Opposite the micropylar end, is the chalaza, representing the basal part of the ovule.The body of the ovule fuses with funicle in the region called hilum.In ovule of most of the plants, funicle is attached to the main body of ovule for some distance (at lateral side) to form a ridge like structure known as raphe.
