The Basidiomycetes or the Ascomycetes are 2 main groups of fungi .
In the Basidiomycetes, the spores are produced externally, on the end of specialised cells called basidia.
In Ascomycetes, spores are produced internally, inside a sac called an ascus.
Asci and basidia are both microscopic structures.
Spores are produced by meiosis .
Basidiomycetes
Ascomycetes
Fungi with spores produced externally, on specialised cells called basidia.
Typically, there are 4 spores per basidium .
Fungi with spores produced inside a sac called an ascus.
Each ascus usually contains 8 spores produced by meiosis followed by mitosis .
Ascomycetes produce spores in sac-like structures called asci, while basidiomycetes produce spores on club-shaped structures called basidia. Basidiomycetes typically have a more complex fruiting body structure compared to ascomycetes, often forming mushrooms. Additionally, ascomycetes tend to reproduce asexually through conidia more frequently than basidiomycetes.

Which structure is typical of the basidiomycetes but not the other two groups?
Basidiomycetes are characterized by the presence of basidia, which are club-shaped structures that produce spores externally. This type of spore formation is unique to basidiomycetes and not found in ascomycetes or zygomycetes.
What are the classifications of fungi according to the ability to reproduce?
Fungi can be classified into two groups based on their ability to reproduce sexually: Ascomycetes (sac fungi) and Basidiomycetes (club fungi). Ascomycetes produce spores in sac-like structures called asci, while Basidiomycetes produce spores on club-shaped structures called basidia.
What is septate hypha?
Septate hypha is a type of fungal hypha that is divided into compartments by septa, which are cross-walls containing pores that allow for the flow of nutrients and organelles between the compartments. These septa help in compartmentalizing the hyphae and are a distinguishing feature of certain fungi, such as Ascomycetes and Basidiomycetes.
Is threadlike fungi unicellular?
Ascomycetes and Basidiomycetes are not. Filamentous chytrids and zygomycetes can be considered unicellular if there are no septa in their hyphae. For the most part, threadlike fungi are considered multicellular.
Why is penicillin placed in the group ascomycetes though sexual reproduction is absent in them?
Because penicillin is made out of the fungus ascomycetes.

What are the main groups of fungi?
There are five main groups of fungi: Ascomycetes, Basidiomycetes, Chytrids, Deuteromycetes, and Zygomycetes
What are the classifications of fungi according to the ability to reproduce?
Fungi can be classified into two groups based on their ability to reproduce sexually: Ascomycetes (sac fungi) and Basidiomycetes (club fungi). Ascomycetes produce spores in sac-like structures called asci, while Basidiomycetes produce spores on club-shaped structures called basidia.

These septa help in compartmentalizing the hyphae and are a distinguishing feature of certain fungi, such as Ascomycetes and Basidiomycetes.
Which structure is not found in a mushroom a ascus b gills c cap d stalk?
Ascus is not found in a mushroom. Ascus is a structure present in types of fungi such as ascomycetes. Mushrooms belong to the group of fungi known as basidiomycetes, which have gills (or pores), cap, and stalk.
What is the difference between ascomycetes and zygomycetes?
Ascomycetes produce their spores in sac-like structures called asci, while zygomycetes produce their spores in sporangia. Additionally, ascomycetes often have a more complex structure with septate hyphae, while zygomycetes typically have a simpler structure with coenocytic hyphae.
What is different between ascomycetes and phycomycetes?
Ascomycetes have specialized spore-bearing structures called asci, while phycomycetes produce spores in sporangia. Ascomycetes have a sexual reproductive structure called ascocarp, whereas phycomycetes lack a well-defined sexual reproductive structure. Additionally, ascomycetes typically have septate hyphae, while phycomycetes have coenocytic hyphae (lacking septa).
What division is the mushroom a member of?
Mushrooms belong in the Division Dikarya (Or also called Basidiomycota) in the Kingdom of Fungi. This is divided down to the phylum Ascomycetes, home to cup fungi, beech orange, dead man's fingers and more, and the phylum Basidiomycetes which holds all the true mushrooms, as well as stinkhorns, truffles & more.
Is threadlike fungi unicellular?
Ascomycetes and Basidiomycetes are not. Filamentous chytrids and zygomycetes can be considered unicellular if there are no septa in their hyphae. For the most part, threadlike fungi are considered multicellular.
What is dolipore septum?
The dolipore septum is a pore-like structure found in the cell walls of certain fungi, particularly in Basidiomycetes and some Ascomycetes. It serves as a gatekeeper, regulating the flow of cytoplasm and nutrients between cells. Additionally, it plays a role in the formation and release of spores.
Why is penicillin placed in the group ascomycetes though sexual reproduction is absent in them?
Because penicillin is made out of the fungus ascomycetes.
What fungi forms basidia?
Basidiomycetes are the fungi group that form basidia. Basidia are specialized cells that produce basidiospores, the sexual spores of basidiomycetes. Common examples of basidiomycetes include mushrooms, bracket fungi, and puffballs.
