saprotrophic decomposer
|
Organism that secretes digestive enzymes and absorbs the resulting nutrients back across the plasma membrane.
|
|
|
parasitic
|
Species that is dependent on a host species for survival, usually at the detriment of the host species.
|

mycelium
|
Tangled mass of hyphal filamients composing the vegetative body of a fungus.
|
|
|
hyphae
|
Filament of the vegetative body of a fungus.

|
|
chitin
|
Strong but flexible nitrogenous polysaccharide found in the exoskeleton of arthropods.
|
|
|
spore
|
Asexual reproductive or resting cell capable of developing into a new organism without fusion with another cell, in contrast to a gamete.
|
|
|
budding
|
Asexual form of reproduction whereby a new organism develops as an outgrowth of the body of the parent.
|
|
|
fragmentation
|
A form of asexual reproduction in which a portion of a mycelium begins a life of its own.
|
|
|
ascus
|
Fingerlike sac in which nuclear fusion, meiosis, and ascospore production occur during sexual reproduction of sac fungi.
|
|
|
fruiting body
|
Spore-producing and spore-disseminating structure found in sac and club fungi.
|
|
|
cap
|
The shape of the ascocarp in club fungi which is a type of fruiting body.
|
|
|
annulus
|
On mushrooms, the part of the stalk located high on the stalk right below the gills and cap.
|
|
|
gills
|
On mushrooms, the bottom of the cap where the lamelle radiate and basadia are located.
|
|
|
stalk
|
Long portion of the mushroom that holds the gills and cap in the air.

|
|
basidium
|
Clublike structure in which nuclear fusion, meiosis and basidiospore production occur during sexual reproduction of club fungi.
|
|
|
basidia
|
On a mushroom, lines the extensive surface area of the basidiocarp. Nuclear fusion, meiosis, and spore production occur here.
|
|
|
lichens
|
Symbiotic relationship between certain fungi and algae, in which the fungi possibly provide inorganic food or water and the algae provide organic food.
|
|
