Diagram showing a yeast cell Several yeasts, in particular S. cerevisiae and S. pombe , have been widely used in genetics and cell biology, largely because they are simple eukaryotic cells, serving as a model for all eukaryotes, including humans, for the study of fundamental cellular processes such as the cell cycle , DNA replication ...
Yeast cells are normally protected by a thick cell wall which makes extraction of cellular proteins difficult. [ citation needed ] Enzymatic digestion of the cell wall with zymolyase, creating spheroplasts, renders the cells vulnerable to easy lysis with detergents or rapid osmolar pressure changes.
Candida albicans growing as yeast cells and filamentous (hypha) cells. A dimorphic fungus is a fungus that can exist in the form of both mold [1] and yeast.As this is usually brought about by a change in temperature, this fungus type is also described as a thermally dimorphic fungus. [2]

The cell achieves its height in the water column by synthesising gas vesicles. As the cell rises up, it is able to increase its carbohydrate load through increased photosynthesis. Too high and the cell will suffer photobleaching and possible death, however, the carbohydrate produced during photosynthesis increases the cell's density, causing it ...
