Summary
| DescriptionПроводящий пучок Pteridium aquilinum.JPG |
Русский: Амфикрибральный проводящий пучок корневища папоротника Орляк обыкновенный (лат. Pterídium aquilínum). Крупные клетки с красной клеточной оболочкой - это клетки ксилемы. Вокруг ксилемы расположены клетки паренхимы ксилемы и клетки флоэмы. Однорядный слой мелких клеток, расположенных по окружности (с содержимым красного цвета) - это эндодерма. В основной паренхиме видны амилопласты, запасающие крахмал.
Авторский постоянный препарат, полихромная окраска тканей.

English: 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 Light microscopy, bright-field in transmitted light Français : Zoom microscopique sur le faisceau cribro-vasculaire d'une grande fougère (Pteridium aquilinum)Les grandes cellules avec des parois rouges sont des trachéides. Elles jouent un rôle dans le transport de l'eau. Autour du xylème se trouvent les parenchymes et les cellules de phloème. La couche constituée d'une seule rangée de petites cellules rouges le long de la circonférence est l'endoderme. Dans les parenchymes, il y a des amyloplastes qui stockent les granules d'amidon.

Las células grandes, con paredes de glóbulos rojos, son traqueidas. Sirven en el transporte de agua. Alrededor del xilema hay células de parénquima xilemático y floema. Una capa de una sola fila de células pequeñas (con contenido rojo) ubicadas circunferencialmente es el endodermo. En el parénquima hay amiloplastos que almacenan gránulos de almidón. Українська: Амфікрибральний судинний пучок кореневища папороті орляк звичайний (Pterídium aquilínum). Великі клітини з червоною клітинною оболонкою — це клітини трахеїди (мертві клітини ксилеми). Навколо ксилеми розташовані клітини паренхіми ксилеми та клітини флоеми. Однорядний шар дрібних клітин, розташованих по колу (з вмістом червоного кольору) — це ентодерма. В основній паренхімі видно амілопласти, що запасають крохмаль. العربية: حزمة وعائيَّة مركزية الخشب في جذمور الخِنْشار كبير. الصورة مكبرةٌ باستعمال الاستجهار الضوئي. الخلايا الكبيرة ذات الجُدر الحمراء هي القُصيبات، والتي تعمل على نقل الماء. يُحيط بها النسيج الحشوي للنسيج الوعائي الخشبي بالإضافة إلى خلايا اللحاء. هناك طبقةٌ واحدةٌ من الخلايا الصغيرة حمراء المحتوى، وهي الأديم الباطن. |
