Yes, yeast does have a Golgi apparatus, although its morphology can vary between different species.
The Golgi apparatus is an essential organelle in eukaryotic cells responsible for processing and packaging proteins and lipids. While its presence is consistent across yeast species, its physical structure isn't always the same.
Here's a breakdown:
-
Saccharomyces cerevisiae (Budding Yeast): In this commonly studied yeast species, the Golgi exists as a system of dispersed cisternae. This means, instead of being organized in stacked structures like in mammalian cells, the Golgi cisternae are scattered throughout the cytoplasm.
-
Pichia pastoris and Schizosaccharomyces pombe: Unlike S. cerevisiae, these yeast species exhibit Golgi cisternae that are organized into stacks, resembling the Golgi structure found in other eukaryotic organisms.
| Yeast Species | Golgi Morphology |
|---|---|
| Saccharomyces cerevisiae | Dispersed cisternae |
| Pichia pastoris | Stacked cisternae |
| Schizosaccharomyces pombe | Stacked cisternae |
In summary, the Golgi apparatus is present in yeast, carrying out essential functions in protein and lipid processing. However, the organization of the Golgi, specifically whether it exists as dispersed cisternae or stacked cisternae, differs depending on the yeast species.
