Items are located in tubules of primary cellular cover; in cells with a secondary cover they are localized only in the closing films of a time of a cell wall. In P. plasma membranes of the next cells pass each other; the tubular structures passing in P. are connected with vacuoles and tanks of a cytoplasmic reticulum.

At mitotic division of plant cells in cellular plates (phragmoplasts), to-rye form right after completion of nuclear fission and differentiate cytoplasm of daughter cells, the microtubules and bubbles of a cytoplasmic reticulum defining future

P. P.' arrangement are localized play an important role in circulation of liquid between plant cells, maintenance of their turgor, transfer of irritations and so forth
