Description and Significance
Malassezia globosa is a type of yeast whos habitat is within the human body. It is thought to be harmless because it adds to the overall health of a human, but it does have instances of being malicious. It is a circular fungi that with a microscopes help, can be seen in a large population in cells along with its spores.

Cell Structure, Metabolism and Life Cycle
Like other eukaryotic organisms, the yeast cell has a well-organized nucleus bound in a membrane. Malassezia are the same due to their position as a fungi. The nucleus contains double-stranded chromosomes that pass along DNA during reproduction. Unlike plants, yeast are heterotrophs that do not have chlorophyll, a vascular system or a cell wall made of cellulose.The cell structure and function of yeast sets it apart from cells in plants, animals and bacteria. Yeast is a prolific, single-celled fungus that plays a major role in the food, beverage and pharmaceutical industry. When yeast cells are deprived of food, the cytoplasm in the cells becomes more acidic and proteins interact, causing the cytoplasm to become less fluid. Cell activity then slows to preserve the cell in the absence of an energy source. For instance, a package of dry yeast purchased at the store sits dormant until conditions for growth are right.

Ecology and Known Roles in Symbiosis
In what habitat(s) do you find this microbe? What roles (if known) does this microbe play in symbiosis with other organisms? What role or contribution does this microbe contribute to the environment.
Fun Facts
The importance of malassezia is that it is apart of every humans daily life. The average person will have about 10 million of them on heir scalp at a time. This fungi cause common skin rashes, which can be treated quickly. It causes dry scalp which affects many people.
