Document Summary
Mutualism- positive interactions between individuals of different species that benefit at least one partner but don"t cause harm to the other. Facultative mutualism: mutualism occurs when a species can live without its mutualistic partner. Obligate mutualism: mutualism when a species is dependent on a mutualistic relationship. The species can"t live without the other one. 15. 1 plant mutualisms: plants benefit from mutualism partnerships with a wide variety of bacteria, fungi, and animals. There is a fungus named mycorrhizae that live in the roots of plants. The two most common types of mycorrhizae are : Arbuscular mycorrhizal fungi (amf) in which the mycorrhizal fungus produces arbuscules sites of exchange between plants and fungus. hyhpae are fungal filaments and vesicles fungal energy storage organs within root cortex cells. Ectomycorrhizae (ecm) the fungus forms a mantle around roots and netlike structure around root cells.
