BIOL 102 – UNIT IV: Fungi Study Guide

A set of vocabulary flashcards focusing on key terms and definitions related to the characteristics, morphology, classification, and physiology of fungi.

Eukaryotic

Organisms with a true nucleus.

Heterotrophic

Organisms that cannot make their own food and absorb nutrients.

Saprobes

Organisms that feed on dead organic material.

Parasites

Organisms that feed on living hosts.

Mutualistic symbionts

Organisms that live in partnership to benefit each other, such as fungi with algae in lichens.

Septate hyphae

Hyphae with cell walls and pores allowing the flow of cytoplasm.

Coenocytic hyphae

Hyphae that lack cell walls and membranes, with no septa between cells.

Mycelium

A mass of connected hyphae that grows through and penetrates the substrate.

Sporocarp

The fruiting body of fungi that produces spores.

Lichens

A mutualistic relationship between fungi and algae or cyanobacteria.

Chitin

A polysaccharide that provides structural stability in fungal cell walls.

Mycorrhizae

A symbiotic relationship between fungi and plant roots.

Conidiogenesis

The production of asexual spores called conidia.

Mutualism

A type of symbiotic relationship where both parties benefit.

Fungal cell wall components

Includes mannoproteins, glucans, chitin, and the plasma membrane.

Fungi reproduction

Occurs via spores, which can be sexual or asexual.

Ascomycota

Also known as 'sac fungi', characterized by ascospores produced in sac-like asci.

Basidiomycota

Also known as 'club fungi', characterized by spores formed on basidia.

Zygomycota

Fungi that reproduce sexually by forming zygospores.

Deuteromycota

Fungi with no observed sexual reproduction, primarily reproduce asexually.

Spores

Reproductive cells of fungi, which can be formed sexually or asexually.

Fungal physiology

Includes nutritional requirements like carbon, nitrogen, water, and light.

Aeration

Oxygen requirement for fungal respiration.
