Shelby is a plant breeder who is trying to identify the cause of a disease among a group of trees. She observes that the organis
m reproduces through spores and has reproductive structures that are shaped like a sac. Which type of fungus is it? Ascomycota Basidiomycota Chytridiomycota Zygomycota
The phylum Ascomycota is the largest phylum in the Kingdom Fungi. Examples are Yeast, <em>Aspergillus, Neurospora,</em> Members of Ascomycota are called ‘sac fungi’ due to the formation of an ascus, a sac-like structure that contains haploid ascospores. During sexual reproduction, thousands of asci (singular; ascus) are formed in a fruiting body called the ascocarp. The diploid nucleus gives rise to haploid nuclei by meiosis. The ascospores are formed in each ascus after meiosis. On maturity, ascospores are released in the new environment and germinate to form hyphae and start new mycelia.
