Fungi

Biologists use the term ‘fungus’ to include eukaryotic, spore-bearing, achlorophyllous organisms that generally reproduce sexually and asexually. They are usually made up of filamentous, branched somatic structures which are typically surrounded by cell walls containing chitin or cellulose, or both of these substances. The fungi originated as a distinctive group …

A fungi is a group of eukaryotic heterotphic organisms members of which have chitinous cell wall and are differentiated from other living organisms by their special vegetative structure   and nutrient intake. Members of this group include yeast, rusts, mildews, molds, mushrooms etc. Mycology The discipline of bioscience that deals with …

In the kingdom Fungi, there are two major phyla- Ascomycota and Basidiomycota. These two together form a subkingdom of fungi named as Dikarya. They together were named such as members of both phyla maintain most part of their life cycle in dikaryotic stage meaning each cell contains two genetically different …

INTRODUCTION Ascomycota is a phylum of fungi classification containing a compartmentalized mycelium, a dikaryotic life stage in the life cycle, plectenchymatous structures associated with spore production, conidia, and sometimes complex dispersal systems. The primitive morphological character that distinguishes members of Ascomycota from all other fungi is the Ascus (pl. asci, …
