Development of Ovule

The ovule develops from a specialised region of the ovary - the placenta. Initially it appears as a small mound on the placenta, and is composed of homogenous tissue. Subsequently it cuts off initials for the integuments, and undergoes specific degree of curvature to develop as a mature ovule. We shall resume discussion on the structural and developmental aspect of ovule later when you study integuments.
