Female pine cone scale. Light micrograph of a section through a scale from a young ovulate female pine (Pinus sp.) cone, bearing an ovule (upper centre). The ovuliferous scale (purple) sits under the archegonium, which is enclosed by two integuments - the outer (blue-grey) and the inner (large cells, blue). The ovule (blue) develops several archegonia each with one egg (brown). Magnification: x13 when printed 10 centimetres wide.
