Pine Cone Female (Longitudinal Section)
Pinus
A longitudinal section of a female pine cone or ovulate megastrobilus (Pine Cone - Female L.S.) stained with Fast Green. The central axis supports spirally arranged megasporophyll complex structures, each consisting of an ovuliferous scale bearing ovules on its upper surface, subtended by a small bract scale. Within the ovules, key gymnosperm reproductive anatomy is visible, including the integument, micropyle, megasporangium (nucellus), and developing female gametophyte (megagametophyte). This section demonstrates gymnosperm reproductive morphology and seed-cone organization.
