Rapeseed Flower Bud (Cross Section)
Brassica napus
This transverse section through a rapeseed (Brassica napus) floral bud displays the complete concentric arrangement of floral whorls typical of Brassicaceae. Enclosing the exterior are the outer sepals (calyx) and delicate petals (corolla). Positioned centrally within the whorl are multiple tetradynamous stamens, whose anthers reveal distinct pollen sacs (microsporangia) filled with developing microspores/pollen grains. At the absolute center of the bud section sits the superior ovary, composed of two fused carpels separated by a false septum (replum) with developing ovules attached along parietal placentas. Fast Green counterstaining clearly outlines the cellular architecture, vascular bundles, and protective dermal tissues across all floral organs.
