Living Organisms II - Mycology Topic No. 2

Vocabulary flashcards covering key concepts in fungal nutrition and growth from mycology.

Aerobic

Organisms that require oxygen for their survival.

Facultative anaerobes

Organisms that can survive with or without oxygen, such as certain yeasts.

Mesophilic

Species that thrive at moderate temperatures.

Heterotrophs

Organisms that require organic carbon for growth and exhibit absorptive nutrition.

Saphrophytes

Organisms that feed on dead or decaying organic matter.

Parasites

Organisms that live on or in a host and obtain nutrients at the host's expense.

Haustoria

Specialized structures that allow parasites to invade host cells.

Ecto-mycorrhizas

Fungal structures that form a sheath around plant roots.

Endo-mycorrhizas

Fungal structures that penetrate the root cells of plants.

Hyphae

The typical eukaryotic structures of fungi, composed of long filaments.

Aseptate hyphae

Hyphae without cross walls, typically found in Chytridiomycetes and Zygomycetes.

Septate hyphae

Hyphae containing cross walls (septa) that separate compartments.

Dolipore septum

A barrel-like structure that allows the flow of protoplasts and contains a pore.

Chitin

A structural polysaccharide found in the cell walls of fungi.

Vesicles

Small membrane-bound structures that transport materials in cells.

Rhizomorphs

Thick, root-like strands that help fungi to transport water and nutrients.

Sclerotia

Small, rounded structures that serve as resting bodies for fungi.

Plectenchyma

Organized fungal tissues that can be classified as prosenchyma or pseudoparenchyma.
