a mass of hyphae which form a visible structure and perform a specific function in a fungus

mycelium

Fungi are classified as saprophytes when they exhibit which characteristic?

obtain food from non-living organic material

An organism which lives directly on or in another organism without providing any benefits to its host is called a:

parasite

an organism that grows, feeds, and is sheltered on or in a different organism while contributing nothing to the survival of its host.

parasite

antibiotic formed by Penicillium chrysogenum, which when discovered opened a whole new world of medicine

penicillin

level of taxon below kingdom, also called division in the plant and plant-like kingdoms

phylum

an organism whose cells do not contain a nucleus that is bound by a membrane

prokaryote

Without spores, fungi could not:

reproduce

mycelia responsible for obtaining food from the non-living organic matter on which a fungus is growing
