| Ovule | The organ that after fertilization becomes the seed. The ovule in angiosperms contains the embryo sac with an egg cell, several other cell types, and is enclosed within the locule of the ovary. |  |
| Ovule | The organ that contains the egg and, after fertilization, becomes the seed. The ovules are included within locules of an ovary and are attached to the placenta in different ways that, in some cases, are generic specific. |  |
| Ovule anatropous | Referring to a curved downward ovule in such a way that the micropyle is close to the funicular attachment. |  |
| Ovule bitegmic | An ovule with two integuments. |  |
| Ovule campylotropous | Referring to an ovule in which the axis is at an approximately right angle to its stalk (funicle). |  |
| Ovule columns | The number of vertical lines of ovules from the base to the apex of the placenta. The number of horizontal layers of ovules in a locule. A longitudinal section that removes the outside wall of a locule allows this feature to be seen with the most accuracy. It can also be observed in a medial longitudinal section. A longitudinal section that removes the outside wall of a locule allows this feature to be seen with the most accuracy. It can also be observed in cross sections through the placenta. |  |
| Ovule horientation oblique | A type | |
| Ovule insertion | Referring to where ovules are inserted along the lower septum as viewed in longitudinal section. |  |
| Ovule orientation | The relationship between the direction that an ovule departs from the middle of the placenta in relation to the long axis of the ovary (equals the orientation of the lower/upper septum), as seen in a medial longitudinal section. | |
| Ovule orientation horizontal | Refers to an ovule that departs from the middle part of the placenta at a more-or-less 90 degree angle as seen in longitudinal section. |  |
| Ovule orientation oblique | An ovule that departs from the middle part of the placenta at an angle less than 90 degrees as seen in a longitudinal section. The angle is the upper angle of a line drawn through the ovules and intersecting with the vertical axis of the ovary as seen in longitudinal section. |  |
| Ovule orientation pendulous | An ovule that departs from a poorly developed placenta that hangs downward at the apex of the locule as seen in a longitudinal section of the ovary. |  |
| Ovule orthotropous | Referring to a straight ovule in which the micropyle is positioned in a straight line and opposite the funicular attachment; referring to a growth habit in which the growing apex is oriented vertically. | |
| Ovule rows | The number of horizontal layers of ovules in a locule. A longitudinal section that removes the outside wall of a locule allows this feature to be seen with the most accuracy. It can also be observed in a medial longitudinal section. A longitudinal section that removes the outside wall of a locule allows this feature to be seen with the most accuracy. | |
| Ovule unitegmic | An ovule with one integument. | |
| Unitegmic ovule | An ovule with one integument. | |
