The phylum Ascomycota (colloquially called ascomycetes) is by far the largest group of fungi, estimated to include more than 32000 described species in 3400 genera (Kirk et al., 2001). It is assumed that the majority of ascomycetes has yet to be discovered, and the total number of species may well …

With the invention of the microscope by van Leeuwenhoek in the seventeenth century, the systematic study of fungi began. And the man who deserves the honor of being called the founder of the science of mycology is Pier Antonio Micheli, the Italian botanist who, in 1729, published Nova Plantarum Genera, …

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 …

Good to know A living cell can concentrate the solute, dead cell can’t. The suction pump can lift up to 34 ft in 1 atm pressure. Harry Cole tree was the highest plant up to 1988-89. Insoluble substances if added can not alter the osmotic potential. Only soluble substances can. …

The upward movement of water inside the plant is called ascent of sap. Pathway: Xylem. Prove that xylem is the pathway of ascent of sap. 1st experiment A leafy twig of balsum plant…………………………………………. 2nd experiment: Ringing experiment A leafy twig from a tree is cut……………………………………. Mechanism of ascent of sap …

Uptake of water by plants more specifically by plant root hair is called water absorption. It is a vital process in case of plants as uptaken water along with minerals are mandatory for the survival of the plant body. In case of lower plants, the whole body acts as water …

Concept of water potential Free energy per mole is the chemical potential. The water potential is the chemical potential of a water solution in a system minus the chemical potential of pure water at atmospheric pressure and at the same temperature. A system’s water potential expresses its ability to do …

Isotonic, Hypotonic and Hypertonic solution Case A In the cell, Concentration = .1mMol L-1 Ψp is negligible or 0 In the solution of the container, Concentration = .1mMol L-1 Ψp = 0 In both cases, Ψw = Ψπ + Ψp = -CRT (Ψp is 0 or negligible) Comment: There will …

Chemistry is about combining different substances. Sometimes combining substances can cause a chemical reaction and bonding. This creates an entirely new substance called a compound. However, sometimes when there is no chemical reaction or bonding, it forms only a mixture. A mixture is made when two or more substances are …
