Which characteristic primarily differentiates yeast from molds?
Which characteristic primarily differentiates yeast from molds?
- Yeast grow as single cells, while molds grow as multiple tubular branches. (correct)
- Molds can grow in both aerobic and anaerobic conditions, but yeast can only grow in aerobic conditions.
- Yeast are multicellular, while molds are unicellular.
- Yeast reproduce only through spore formation.
In what environmental condition are molds typically found?
In what environmental condition are molds typically found?
- High-temperature, sterile environments.

Study Notes
- The presentation discusses fungi and mould in the context of biomedical science
- By the end of the session, students should be able to differentiate yeast from mould and identify fungal commensal flora and their location
Features of Fungi
- Fungi are eukaryotic organisms
- The most important fungus relevant to dentistry is Candida
- Fungi come in two structural forms: yeast and mould
- Some fungi are dimorphic, meaning they can exist as both yeast and mould
Yeast Characteristics
- Grow as large single cells and are unicellular
- Commonly found on fruit, in the stomach of mammals, and in oral and vaginal areas
- Yeast appears white and thready, usually oval in shape
- Yeasts do not have true hyphae, instead forming multicellular structures called pseudo-hyphae
- Yeast is not a sporing species of fungi
- Yeasts are less colorful compared to moulds, appearing collectively yellow creamy
- Yeast can grow in both aerobic and anaerobic conditions
- Can cause infection in individuals with compromised immune systems
- Often have lateral projections, called daughter cells
- Reproduces asexually mostly, through budding
Mould Characteristics
- Grow as multiple tubular branches and are multicellular
- Typically found in damp, dark, or humid areas
- Appear fluffy and come in several shapes
- Have microscopic filaments called hyphae and are a sporing fungus
- Moulds are very colorful, maybe orange, green, black, brown, pink or purple
- Grow only in aerobic conditions
- Health risks usually consist of allergic reactions and respiratory problems
- Consist of multicellular threads called hyphae
- Hyphae contain cytoplasm and organelles
- Mycelium is a mass of hyphae that forms mould colonies
- Reproduce through spores, with a reproduction that is either be asexual or sexual
Fungal Commensal Flora
- Fungal commensal flora includes species such as Aspergillus, Candida, and Malassezia
- Different fungal species are found in various locations on/in the human body, including the oral cavity, nares, lungs, colon, vagina, skin (palm, antecubital fossa, plantar heel), and toe web space
