fungi notes Flashcards
what are the three types of fungi
Zygomycota
Ascomycota
Basidiomycota
what are fungi
a large group of organisms that can be unicellular or humungous
what are fungi cell walls made of
chitin and polysaccharides
how do fungi reproduce
sexually and asexually
why kind of feeders are fungi
heterotrophs
what are heterotrophs
can photosynthesis but can’t use co2 or find n2
what are the three types of heterotrophs
saprophytes nutrients from dead
necrophytes (like saphrophytes but they kill)
biotrophs- nutrients from a living host
why are fungi good heterotrophs
as they can use a large range of organic carbon sources and can produce a lot of molecules with a good source of carbon and nitrogen.
what are some differences between plants and fungi
plants photosynthesise fungi secrete enzymes for food fungi filametous plants are box like plants are cellulose, fungi are filamentous
where does mitosis in fungi occur
nucleus
what are yeasts
oval shaped single celled organisms
how does yeast reproduce
produces identical daughter cells through asexual reproduction
what can yeast form
a pseudo hypae
what are filamentous fungi
this type makes up the vast majority of fungi, multicellular and produces long thread like hyphae
how do filamentous fungi reproduce
via spores
they can colonise food rapidly. These spores are haploid and are formed from specialised extensions from mycelia.
