mycology
The study of fungus
heterotrophic
An organism that must eat or consume food because it cannot make its own
saprobes
Organisms that get their nutrients from dead or decaying matter
parasites
An organism that lives in or on another organism, and feeds on the host
hyphae
A chain of cells that are threadlike and form the body of a fungus -vegetative part.
mycelium
The part of the fungus responsible for extracellular digestion and absorption of the digested food; the vegetative part of a fungus consisting of a tangled mass of branching threadlike hyphae
stolon
In fungi, a stemlike horizontal hypha in mold that runs along the surface of a food source
rhizoids
Structures in fungus that anchor it in place. It releases digestive enzymes and absorbs what has been digested.
fission
Splitting apart
budding
Asexual reproduction in which a part of the parent organism grows a bud which pinches off and forms a new organism
fragmentation
A means of asexual reproduction whereby a part of the parent breaks off and then grows into a new individual.
dikaryotic (N + N)
In fungus, when a cell has two haploid nuclei for a period of time
haploid (N)
Has half the number of chromosomes or only one set of chromosomes
diploid (2N)
Has the full set of chromosomes or two sets of chromosomes
mycorrhizae
A mutualistic symbiotic relationship between fungal roots and plant roots.
lichens
A mutualistic symbiotic relationship between a sac fungus and a green algae.
sporangiophore
A fungal structure (hyphae) that raises the sporangium away from the food source so that air currents can spread the spores to a different location
spores
A unicellular and microscopic reproductive structure of fungus that is able to develop into new individuals.
sporangium / sporangia
A multicellular organ in fungi in which meiosis occurs to produce haploid spores.
gametes
Reproductive cells that have only half the number of chromosomes
gametangium / gametangia
Produces gametes
fruiting body
Reproductive structures in which fungi produce spores
