What is ascus in botany?
ascus, plural asci, a saclike structure produced by fungi of the phylum Ascomycota (sac fungi) in which sexually produced spores (ascospores), usually four or eight in number, are formed.
What is ascus Class 11?
Hint: Ascomycetes and Basidiomycetes are two major phyla of the kingdom Fungi. Both of these reproduce by means of spores. The Ascomycetes produce spores through sac shaped cells called Ascus. On the other hand, Basidiomycetes produce spores through a club-shaped sac called Basidium.
What is the shape of ASCUS?
Ascus shape (cylindrical, clavate, globose) may be indicative of some species or even genera; in discomycetes and pyrenomycetes, it is typically cylindrical or clavate, and in many cleistothecial ascocarps, it is globose. In some species, asci are evanescent (disintegrate) and must be observed at an early stage.
Does ASCUS mean CIN?
Atypical squamous cells of undetermined significance (ASCUS) is a term that refers to inflammatory, reactive and reparative processes which are atypical and of higher level and insufficient to be classified as cervical intraepithelial lesions (CIN).
What is ascus and basidium?
Ascus is a spherical, cylindrical or club-shaped structure in which usually eight ascospores are formed endogenously. They are the characteristic feature of the members of Ascomycotina. Whereas, basidium is also a club-shaped structure but here basidiospores are formed exogenously on minute stalks, the sterigmata.

What is ascus in fungi?
Fig. 50 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.
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 is the reproductive structure of an ascus?
reproductive structure- the parts of a plant involved in its reproduction ascomycete, ascomycetous fungus- any fungus of the class Ascomycetes (or subdivision Ascomycota) in which the spores are formed inside an ascus Based on WordNet 3.0, Farlex clipart collection. © 2003-2012 Princeton University, Farlex Inc.
What is atypical squamous cell of undetermined significance (ascus)?
ASCUS Atypical squamous cell of undetermined significance Cytology A cell seen in a pap smear of the cervix that fulfills some of the criteria–eg nuclear enlargement and irregularity, cytoplasmic clearing, and thickened cell membranes, that define cells typical of either a condyloma or a neoplasm. See CIN, HSIL, LSIL.
