Colonization of Land by Fungi

Fungi

Eukaryotic organisms essential for nutrient cycling.

Mycorrhizae

Symbiotic associations between fungi and plant roots.

Heterotrophs

Organisms that absorb nutrients from external sources.

Chitin

Strong polysaccharide in fungal cell walls.

Mycelia

Networks of branched hyphae for nutrient absorption.

Hyphae

Filaments that make up the mycelium of fungi.

Haustoria

Specialized hyphae for nutrient exchange with plants.

Spores

Reproductive units for fungal propagation.

Zygomycetes

Fast-growing molds and parasites, including bread molds.

Glomeromycetes

Fungi forming arbuscular mycorrhizae with plant roots.

Ascomycetes

Fungi producing fruiting bodies called ascocarps.

Basidiomycetes

Decomposers with fruiting bodies known as mushrooms.

Chytrids

Fungi with flagellated spores in aquatic habitats.

Lichens

Symbiotic associations between fungi and photosynthetic organisms.

Mutualism

Biotic interaction benefiting both species involved.

Pathogens

Fungi that absorb nutrients from host cells, harming them.

Endophytes

Fungi living inside plant tissues, often beneficial.

Chemical Cycling

Movement of nutrients through ecosystems, altered by fungi.

Biotic Interactions

Relationships between living organisms affecting ecosystems.

Fungal Diversity

Estimated 1.5 million species of fungi exist.

Evolutionary History

Fungi and animals share a closer evolutionary relationship.

Colonization of Land

Fungi and plants partnered to establish terrestrial ecosystems.

Aglaophyton

Fossil evidence of early plant-fungi interactions.

Ecological Roles

Fungi contribute to nutrient cycling and ecosystem health.
