The ovule is straight with funiculus, embryo sac, chalaza and micropyle lying on one straight line. It is Orthotropous.
An orthotropous ovule is one in which no curvature takes place during development the micropyle is positioned opposite the funiculus base.
In the orthotropous ovule the body of these ovules is straight so that the chalaza, where the nucellus and integuments merge, the funicle, which attaches the ovule to the placenta, and the micropyle are all aligned.
