  2. Ovule - Wikipedia

    en.wikipedia.org/wiki/Ovule

    Location of ovules inside a Helleborus foetidus flower. In seed plants, the ovule is the structure that gives rise to and contains the female reproductive cells. It consists of three parts: the integument, forming its outer layer, the nucellus (or remnant of the megasporangium), and the female gametophyte (formed from a haploid megaspore) in its center.

  3. Gynoecium - Wikipedia

    en.wikipedia.org/wiki/Gynoecium

    An ovary with free central placentation, on the other hand, consists of a single compartment without septae and the ovules are attached to a central column that arises directly from the floral apex (axis). In some cases a single ovule is attached to the bottom or top of the locule (basal or apical placentation, respectively).

    Diagram of an ovule in gymnosperms and angiosperms Photomicrograph of an ovule of a monocotyledon In angiosperms the gynoecium , also called pistil , consists of one or more carpels or carpel leaves that form a cavity, the ovary , inside which the ovules or seminal primordia are protected from both desiccation and attack by phytophagous insects.

Placental areas occur in various positions, corresponding to various parts of the carpels that make up the ovary. See Ovule#Location within the plant. An obturator is present in the ovary of some plants, near the micropyle of each ovule.

  9. Egg cell - Wikipedia

    en.wikipedia.org/wiki/Egg_cell

    In seed plants, a structure called the ovule contains the female gametophyte. The gametophyte produces an egg cell. After fertilization, the ovule develops into a seed containing the embryo. [14] In flowering plants, the female gametophyte (sometimes referred to as the embryo sac) has been reduced to just eight cells inside the ovule.
