Basidiomycetes produce a club-shaped cell which bears four protruded haploid spores called basidiospores during sexual reproduction. It is known as basidium (plural: basidia). The key difference between ascus and basidium is that ascus produces ascospores internally while basidium produces basidiospores externally.
What is the difference between a basidium and basidia?
It is a microscopic structure and produces sexual spores called basidiospores. Basidia are developed on the hymenophore of fruiting bodies of basidiomycetes. The presence of basidia is unique to basidiomycetes. A basidium usually produces four basidiospores and occasionally two or eight spores.
What is the difference between basidiomycetes and ascomycetes?
Ascomycetes are one of the phyla in the kingdom Fungi, which are non-mobile, multicellular organisms. 1. In basidiomycetes, basidiospores are produced exogenously on basidium. 1. In ascomycetes, ascospores are produced endogenously inside the ascus. 2. They produce basidiospores. 2. They produce ascospores and conidia. 3.
How do basidiomycetes reproduce?
In basidiomycetes, basidiospores are produced exogenously on basidium. 1. In ascomycetes, ascospores are produced endogenously inside the ascus. 2. They produce basidiospores. 2. They produce ascospores and conidia. 3. Basidiomycetes reproduce asexually by either budding or spore formation. 3. They reproduce asexually by forming conidia. 4.
How many spores are produced from one basidium?
A basidium usually produces four basidiospores and occasionally two or eight spores. However, it can change with the fungal species. Basidia produce narrow prong structures called sterigmata. One basidium produces four sterigmata, and at the tip of the sterigma, each basidiospore is developed externally.

Ascus is a sac-shaped cell which contains ascospores of ascomycetes fungi. It is a microscopic structure, which develops within the mycelial mat, and produces ascospores internally. Usually, ascus contains eight spores inside it. Hence, the name ascus is given to this structure.
What is the meaning of ascospore ascus?
An ascus containing ascospores of Neurospora crassa. (pl. asci) a cell present in the fruiting body of ASCOMYCETE fungi in which the fusion of HAPLOID nuclei occurs during sexual reproduction. This is normally followed by MEIOSIS, giving rise to four haploid cells, after which MITOSIS produces eight ASCOSPORES.
What is the function of the ascus in Ascomycota?
An ascus (or asci in plural) is a saclike structure from which Ascomycota get their name, and it contains the sexual ascospores from which they reproduce. The ascus offers a protective barrier for the ascospores, and in some species may play a functional role in the active dispersal of spores, ejecting them when conditions are favorable.
What does ascus stand for?
There are two categories of ambiguous pathological lesions, namely ASCUS (atypical squamous cells of undetermined significance) and AGUS (atypical glandular cells of undetermined significance). Any Pap report of low-grade squamous intra-epithelial lesions or atypical squamous cells of undetermined significance ( ASCUS) was repeated in 6 months.
What are squamous cells of undetermined significance (ascus)?
One abnormal result you may receive is called “atypical squamous cells of undetermined significance” (also known as ASCUS). Squamous cells are thin and flat and grow on the surface of a healthy cervix.

This structure is known as ascus (plural: asci). Basidiomycetes produce a club-shaped cell which bears four protruded haploid spores called basidiospores during sexual reproduction. It is known as basidium (plural: basidia).
What is the meaning of ascus in fungi?
Ascus is a sac-shaped cell which contains ascospores of ascomycetes fungi. It is a microscopic structure, which develops within the mycelial mat, and produces ascospores internally. Usually, ascus contains eight spores inside it. Hence, the name ascus is given to this structure.
How many spores are in an ascus?
Usually, ascus contains eight spores inside it. Hence, the name ascus is given to this structure. Some ascomycetes fungi produce four ascospores inside the ascus. There are also species with just one spore per ascus and others with over a hundred spores per ascus.
How many species are in the phylum ascus?
It is the largest phylum of Fungi, with over 64,000 species. The defining feature of this fungal group is the ” ascus ” (from Ancient Greek ἀσκός (askós) ‘sac, wineskin’), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed.
Where are ascospores produced in fungi?
Ascospores are produced inside a special reproductive cell called ascus. Ascus is a sac-shaped cell which contains ascospores of ascomycetes fungi. It is a microscopic structure, which develops within the mycelial mat, and produces ascospores internally.

What is the function of Basidium in fungi?
Basidium, in fungi (kingdom Fungi), the organ in the members of the phylum Basidiomycota (q.v.) that bears sexually reproduced bodies called basidiospores.
What is the other name of Basidium?
Alternative Title: basidia. Basidium, in fungi (kingdom Fungi), the organ in the members of the phylum Basidiomycota (q.v.) that bears sexually reproduced bodies called basidiospores.
How many spores are in a basidium?
A basidium usually bears four sexual spores called basidiospores; occasionally the number may be two or even eight. In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (pl. sterigmata), and is forcibly discharged upon maturity.
What is the function of a sterigma in a basidium?
In a typical basidium, each basidiospore is borne at the tip of a narrow prong or horn called a sterigma (pl. sterigmata), and is forcibly discharged upon maturity. The word basidium literally means little pedestal, from the way in which the basidium supports the spores.
