Differentiation of the vegetative apex on Cystoseira stricta Sauvageau involves changes in morphology of the Golgi apparatus. In primary meristematic apical cells, the Golgi bodies remain small in size and secretion vesicles are absent. In meristoderm cells, dictyosomes tend to be hypertrophied.
In inner promeristem cells, they do not seem to participate in a hypersecretory function. Besides Golgi bodies with typical form, we met ring-shaped dictyosome cisternae. These Golgi bodies are normally functioning structures and not significant alterations.
The Golgi apparatus is modified by many different kinds of injuries reduced oxygen atmosphere, prolonged emersion, total absence of the light, decrease in the salinity. But these injuries do not produce any increase of the number of annular cisternae.
The experimental changes described consist of a decreased production of secretory vesicles, a fragmentation and a vacuolation of the Golgi apparatus. This is a preview of subscription content, log in to check access. Rent this article via DeepDyve.
