Summary[edit]

Description
Русский: Проводящий пучок корневища папоротника Pteridium pinetorum ssp. sibiricum. Использован авторский постоянный препарат Михальцова А.И, полихромная окраска тканей по Михальцову А.И. (2012 г.). В результате очень хорошо видны клетки проводящих тканей: крупные клетки, клеточные стенки которых окрашены в красновато-фиолетовый цвет, это клетки ксилемы - водопроводящей ткани. Вокруг ксилемы расположены клетки флоэмы – ткани, проводящей продукты фотосинтеза. Проводящий пучок ограничен клетками эндодермы. Между флоэмой и эндодермой хорошо видны клетки перицикла. Вокруг проводящего пучка расположены клетки паренхимы и склеренхимы (коричневые клеточные оболочки).
English: Conductive bunch of rhizomes of fern Pteridium pinetorum ssp. sibiricum. The author used the constant preparation by A.I. Mikhaltsov, polychrome dyeing of tissues according to A.I. Mikhaltsov (2012). As a result, cells of conductive tissues are very clearly visible: large cells whose cell walls are painted in reddish-purple color are cells of xylem, a water-carrying tissue. Cells of the phloem tissue, conducting the products of photosynthesis, are located around the xylem cell. The conductive beam is bounded with cells of the endoderm. Cells of the pericycle are clearly visible between the phloem and endoderm. Parenchyma and sclerenchyma cells (brown cell wall) surround the conductive beam.
