kingdom fungi Flashcards
what is the cell structure of fungi?
unicellular (yeast) or multicellular
what is the overall structure of fungi :
-network of filaments make up the body (hyphae)
-branching network of hyphae (mycelium)
-division on hyphae (septa)
What is fungis cell wall made up of?
CHITIN
what is the mode of nutrition for fungi?
-heterotrophs
-absorb food
-decomposers
What is extracellular digestion
food is digested outside the cell
how does fungi digest food?
enzymes secreted to digest food externally and is then absorbed by fungus through hyphae
what is Fragmentations mode of reproduction for fungi and is it asexual or sexual
-pieces of hyphae break off and grow into mycelia
-they’re asexual
define Spores mode of reproduction?
-wind blown reproductive structures like pollen
-spores can make copies of themselves
how are fungus mainly classified?
mainly based on their reproduction structre
MAJOR PHYLA FOR FUNGI
define Zygomycotes:
-bread and fruit moulds
-Takes food and nutrients from bread and damages its surface
-grows better on whole wheat bread since it has more nutrients
MAJOR PHYLA FOR FUNGI
define basidiomycotes
lawn mushrooms
Decomposers
Symbiotic relationship with plants
MAJOR PHYLA FOR FUNGI
define Ascomycotes and what they cause
, yeast and
Cause serious plant diseases
MAJOR PHYLA FOR FUNGI
define deuteromycotes
imperfect fungi
Produce spores called conidia
what is the major role of fungi in the ecosystem?
Their decomposers and recycle nutrients
what is fungi, industrial/economic benefit?
makes Food, bread, soy, and mushrooms,
what destruction does fungi cause?
10 to 50% of food production is destroyed by fungi
what is penicillium and what does it kill
Fungus used to make penicillin and kills bacteria
What enzyme does some bacteria produce to resist against penicillin?
beta lactamase
define parasitic fungi and what they cause
-parasistic of plants and animals
-cause athletes foot and ringworms
Define ringworms
-ringworm is a condition caused by fungal infection of the skin
- thrive on warm and moist skin
-feed on keratin
define symbiotic fungi Mycorrhiza
-hyphae from fungus grow around plant root cells
symbiotic fungi
define Lichens
pale moss, which grows on trees
-have symbiotic relationships between fungi, and cyanobacteria
