Fungi Groups and Cell Morphology Quiz

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.
