05 Part 4 Lichens and Part 5 Slime Moulds

Lichens

Symbiotic organisms made of an alga or cyanobacterium with a fungus and sometimes a yeast

Symbiotic relationship

Close relationship between different organisms living together

Symbionts

Organisms involved in a symbiotic relationship

Mutualism

Symbiotic relationship where all organisms benefit

Alga

Photosynthetic organism found in lichens

Cyanobacterium

Photosynthetic bacteria sometimes found in lichens

Filamentous fungus

Fungus with threadlike hyphae found in lichens

Yeast

Third organism possibly embedded in the cortex of lichens

Cortex

Outer layer of a lichen where yeast may be found

Protists

Group in which lichens are classified

Antibacterial properties

Ability to kill or inhibit bacteria

Mosses

Plants often mistaken for lichens

Lichen-covered rocks

Rocks commonly mistaken as moss-covered

Tree trunks

Common surfaces where lichens grow

Rocks
