you are: the Cage of a green plant

Diktiosoma, or device Goldzhi, is large organel-la diskovidnoj the forms, consisting of densely packed membrannyh the tanks which are carrying out sekretornuju function (fig. 2.27). Dense vials are connected With tanks and larger vakuoli; apparently, both those and others arise, gemmating from tanks. As diktiosomy are visible only in electronic microphotos, and for electronic microscopy of a cage it is necessary to kill, track directly relative moving of separate parts diktiosom it is not obviously possible.

However, using a method of serial cuts, it is possible to come to a conclusion that in tanks diktiosom synthesis polisaharidov a cellular wall proceeds and that in vials the synthesised material is transported to cage periphery. eventually vials merge with a plasmatic membrane and the synthesised material otlagaetsja out of a protolayer. Assume that the new material for a cellular wall passes this way from a place of synthesis to an adjournment place. More low we will see that in a cellular wall contain as well some fibers, in synthesis and which secretion in common participate diktiosomy and rough endoplazmatichesky retikulum.

Uploshchennye membrannye tanks have a thickness about 15 nanometers, and width intratsisternalnogo spaces makes 20-30 nanometers. The thickness of all complex as a whole varies depending on number of tanks. According to some cytologists, in a cage there is the continuous network of membranes including a nuclear membrane constantly changing the configuration, endoplazmatichesky retikulum, diktiosomy and plazmalemmu. Similar ' membrannuju a network ', postulated by this still disputable theory, it would be possible, obviously to consider as the mechanism providing fast communication between a cellular kernel and an environment.
