The Golgi body is a group of stacked membranes that deposits material to the cell wall. It is very active during cell division to form new cell walls. It consists of stacks of cisternae that collect cell wall materials and bud off vesicles to migrate to the plasma membrane and empty their contents into the cell wall.

Golgi bodies

Golgi body (also called the


dictyosome) is a group of
stacked membranes responsible
for depositing material to the
cell wall.

Golgi bodies are very active


during cell division when new cell
wall material is needed to form
at the cell plate.

The golgi body consists of two Secretory cisternae


to seven stacks of cisternae
Vesicles
that are grouped but not
connected.

New cisternae form on the


opposite side to the secretory
face of the golgi body as
cisternae are lost to the
production of vesicles.

Golgi bodies

Cell wall materials (mainly


polysaccharides) collect in the
cisternae and eventually vesicles
containing the materials bud off.

Vesicles migrate to the plasma


membrane where they fuse with
the membrane and empty their
contents to the cell wall.
