Amphycribral Vascular Bundle of a Fern Rhizome - Pterídium aquilínum

Big cells with red cell wall are tracheids. They serve in the transport of water. Around the xylem there are xylem parenchyma and phloem cells. A single row layer of small cells (with red content) located circumferentially is endoderm. In the parenchyma there are amyloplasts which store starch granules. Authorial prepared mount, polychrome painted tissues
