What is the relationship between ascocarp and apothecium?
What is the relationship between an ascocarp and an apothecium? An apothecium is a cup-like fungus that has ascu lining the upper surface; it is a cup-like ascocarp. How does the fungal component of a lichen obtain its food? What type of cell division results in the production of spores by conidiophores?
What are the 4 types of ascocarps?
There are four types of ascocarps recognized; cleistothecium, perithecium, apothecium and ascostroma. The latter is a acavity that has been produced in a stroma to accomodate the asci and ascospores.
Is ascocarp haploid or diploid?
The fruiting body is covered with thousands of asci, which is called ascocarp. The diploid nucleus present in each ascus gives rise to the development of haploid nuclei by meiosis and spore walls are developed around each nucleus.
What is ascocarp composed of?
An ascocarp, or ascoma (plural: ascomata), is the fruiting body (sporocarp) of an ascomycete phylum fungus. It consists of very tightly interwoven hyphae and millions of embedded asci, each of which typically contains four to eight ascospores.
How does apothecium differ from Cleistothecium?
The key difference between apothecium and cleistothecia is that apothecium is capable of shooting out spores while cleistothecia are not capable of shooting out spores. Ascomycota is one of the phyla of fungi. They possess different structures to hold the spores.
What is ascocarp how is it formed?
It arises from vegetative filaments (hyphae) after sexual reproduction has been initiated. The ascocarp (in forms called apothecium, cleistothecium [cleistocarp], or perithecium) contain saclike structures (asci) that usually bear four to eight ascospores.
What is apothecium in botany?
apothecium. / (ˌæpəˈθiːsɪəm) / noun plural -cia (-sɪə) botany a cup-shaped structure that contains the asci, esp in lichens; a type of ascocarp.
Is ascocarp a fruiting body?
An ascocarp, or ascoma (plural: ascomata), is the fruiting body (sporocarp) of an ascomycete phylum fungus. Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia).
What is the shape of its ascocarp?
Ascocarps are most commonly bowl-shaped (apothecia) but may take on a spherical or flask-like form that has a pore opening to release spores (perithecia) or no opening (cleistothecia).
What is the difference between ascocarp and Basidiocarp?
The key difference between Ascocarp and Basidiocarp is that the ascocarp is the fruiting body of ascomycete that produces ascospores while the basidiocarp is the fruiting body of basidiomycete that produces basidiospores. Ascocarp and Basidiocarp are two fruiting bodies that bear spores of each group of fungi.
What do you mean by ascocarp?
Definition of ascocarp : the mature fruiting body of an ascomycetous fungus broadly : such a body with its enclosed asci, spores, and paraphyses.
How is an ascocarp different from an apothecium?
The ascocarp is classified according to its placement, but it does not depend on the basics of taxonomy. An apothecium is a fleshy and sessile fruiting body with wide opened saucer-shaped or cup-shaped fungi. The structure of Apothecium consists of three parts. Hymeniun, excipulum, and hypothecium.
Where are the asci located in the apothecium?
The structure of the apothecium chiefly consists of three parts: hymenium (upper concave surface), hypothecium, and excipulum. The asci are present in the hymenium layer. The asci are freely exposed at maturity. An example are the members of Dictyomycetes.
What is the structure of an apothecium fruit?
An apothecium is a wide, open, saucer-shaped or cup-shaped fruit body. It is sessile and fleshy. The structure of the apothecium chiefly consists of three parts: hymenium (upper concave surface), hypothecium, and excipulum. The asci are present in the hymenium layer. The asci are freely exposed at maturity.
What kind of hymenium does an ascocarp have?
(ii) A saucer- or cup-shaped ascocarp with wide open hymenium, an apothecium (pl. apothecia) (Fig. 205G); (iii) A flask-like ascocarp designated as a perithecium (p1. perithecia) (Fig. 206A to C) perforated at the apex by a pore known as ostiole.
