What is Pseudothecia?
pseudothecium (plural pseudothecia) An ascocarp resembling a perithecium but whose asci are not regularly organised into a hymenium and are bitunicate, having a double wall which expands when it takes up water and shoots the enclosed spores out suddenly to disperse them.
What is Perithecia biology?
Definition of perithecium : a spherical, cylindrical, or flask-shaped hollow fruiting body in various ascomycetous fungi that contains the asci and usually opens by a terminal pore.
What is the difference between ascocarp and apothecium?
The ascocarp (in forms called apothecium, cleistothecium [cleistocarp], or perithecium) contain saclike structures (asci) that usually bear four to eight ascospores. Apothecia are stalked and either disklike, saucer-shaped, or cup-shaped with exposed asci.
What is Bitunicate?
bitunicate Applied to an ascus in which the outer and inner layers of the ascus wall separate during ascospore release. A Dictionary of Plant Sciences.
What type of spores are produced in perithecia?
Some perithecia contain mycoparasites in the form of hyphae and thick-walled spores of various sizes. The structure and morphology of the fossil fungus is compared with modern ascomycetes that produce perithecial ascocarps, and characters that define the fungus are considered in the context of ascomycete phylogeny.
What is called Acervulus?
acervulus, an open, saucer-shaped asexual fruiting body found in fungi (kingdom Fungi). Always developed below the epidermis of the host tissue, it bears conidiophores (specialized filaments, or hyphae) that form conidia (spores).
What is the difference between apothecium and perithecium and 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 the difference between ascus and basidium?
The ascus is a sac-like structure that bears reproductive cells. These cells produce sexual spores. Basidium is a club-shaped structure having sexual cells that produce sexual spores.
Where are ascus found?
In many cases the asci are formed in a regular layer, the hymenium, in a fruiting body which is visible to the naked eye, here called an ascocarp or ascoma. In other cases, such as single-celled yeasts, no such structures are found.
What is cleistothecium with example?
Medical Definition of cleistothecium : a closed spore-bearing structure in some ascomycetous fungi from which the asci and spores are released only by decay or disintegration.
What is ascitic fluid in the peritoneal cavity?
The collection of fluid in the peritoneal cavity is called ascites and is called ascitic fluid. An abdominal tap is done on the patient who has unexplained ascites.
What is ascitic fluid and how is it diagnosed?
The ascitic fluid is aspirated from the peritoneal cavity. The collection of fluid in the peritoneal cavity is called ascites and is called ascitic fluid. An abdominal tap is done on the patient who has unexplained ascites. An abdominal tap is done to relieve the intraabdominal pressure. To diagnose whether ascites are benign or due to malignancy.
What is ascites?
What is ascites? Ascites is the accumulation of ascitic fluid in the peritoneal cavity. Many diseases can cause ascites, but the most common cause is portal hypertension, which is usually due to liver cirrhosis. Ascites does not typically become clinically detectable until there are at least 500mLs of fluid present.
What is the most common cause of perihepatic ascites?
This means that liver cirrhosis is the most frequent cause of perihepatic ascites. However, in 10 percent of the cases, the cause of ascites in the perihepatic space is cancer (peritoneal carcinomatosis). Another fairly common cause of ascites in the perihepatic space is heart failure.
