Life Cycles Of Fungi
Acrasomycota (sac fungi)
club fungi
rarely produse asexual spores
spend most of their life cycle as dikaryotic mycelia ,meaning each cell has two nuclei
sac fungi produce both sexually and asexually
1) the fruiting body also know as the "ascocarp" produces zygote
2) the zygote undergoes meiosis and an ascus forms
3) the ascus preforms sexual reproduction and produces ascospores (N)
periodically reproduce sexually by forming basidiocarps , a type of fruiting body
4) the ascospores join and form a single colony
grow rapidly through cell enlargement
composed of basidia ,club shaped hyphae that produce spores
release haploid basidiospores
5) the colony develops into a hypha (N)
6) spores are formed at the tips of the hyphae called conidiophores
common molds life cycle
phylum Zygomycota.
they reproduce both sexually and asexually
Asexual reproduction involves sporangia producing haploid spores.
Sexual reproduction occurs when the environment is no longer favorable.
No defined male and female fungi, just (+) and (-) mating strains
Hyphae produce gametangia, reproductive structures that contain haploid nuclei.
Zygotes can remain dormant for months until the environment becomes favorable.
7) conidiophores produce conidia asexually
