Animal Diversity Part 1B (Fungus)

Fungal Evolution

Monophyletic group, originated from a protist ancestor

Nature’s decomposers and recyclers

Essential for the well-being of most terrestrial ecosystems

Mutualists

Both parties benefit from their presence

Fungus

Multicellular filaments and single cells. Consist of mycelia, networks of branched hyphae adapted absorption

Septate hyphae

Hyphae divided into cells, where pores allow cell to cell movement of organelles

Propagate

To reproduce or spread, often used in reference to plants and organisms. by producing vast numbers of spores either sexually or asexually.

Fungus nucleus

Normally haploid with exception of transient diploid stages formed during the sexual life cycles

Pheromones

Chemical signals released by an organism that influence the behavior or physiology of others of the same species.

Lichen

Symbiotic relationship between fungus and an algae known as ascomycete

Ectomycorrhizal Fungi

Form sheaths of hyphae over a root and also grow into the extracellular spaces of the root cortex

Arbuscular Mycorrhizal fungi

Extend hyphae through the cell walls of root cells and into tubes formed by invagination of the root cell membrane (glomeromycete)

Batrachochytrium Dendrobatids

The amphibian chytrid fungus that makes the skin of amphibians dry out and not absorb moisture.
