Study Notes
Asexual Reproduction in Yeast Cells
- Budding is a mode of asexual reproduction in yeast cells.
Yeast Cell Characteristics
- Yeast cells are typically oval or spherical in shape.
Fungal Groups
- The fungal group known for producing mushrooms is Basidiomycota.
Mold and Filamentous Fungi Cell Types
- Hyphae cells are found in the bodies of molds or filamentous fungi.
Fungal Group Characteristics
- Filamentous fungi are characterized by having long, threadlike cells called hyphae.
Phylum Basidiomycota Characteristics
- The unique clublike structure that defines the phylum Basidiomycota is a basidium.
Basidiomycete Life Cycle
- The basidium contains four haploid nuclei in the life cycle of a basidiomycete.
- The main method of reproduction in basidiomycetes involves the fusion of male and female strains.
Yeast Cell Characteristics
- Pseudohyphae is a chain of yeasts formed when buds remain attached in a row.
Mold Body Structure
- The body or colony of a mold is made up of a mycelium.
Hyphae Functions
- Absorptive hyphae are responsible for digesting and absorbing nutrients in fungi.
Basidium Characteristics
- Basidiospores are formed on the outside of a basidium.
Fungal Divisions
- The fungal division characterized by incomplete septate hyphae and produces basidiospores is Basidiomycota.
- The fungal division where the septa may be incomplete and produce conidia is Ascomycota.
Sexual Spores
- Zygospores are the sexual spores formed after the fusion of two opposite strains in some fungi.
- The key characteristic of zygospores is that they are thick-walled and resistant to environmental stress.
Conidium Characteristics
- A spherical conidium formed by the thickening of a hyphal cell is a chlamydospore.
- A characteristic feature of conidia that distinguishes them from other types of spores is that they are produced from the tips of specialized hyphae.
Lichens
- The main function of algae in lichens is to provide nutrients through photosynthesis.
Conidium Formation
- Microconidium and macroconidium are formed by the same fungus under different environmental conditions.
- Blastospore is a spore produced by budding from a yeast parent cell.
