I MSC MICROBIOLOGY
General Characteristics of Fungi
• The word fungus (plural fungi) is derived
from the Latin word ‘fungus’ meaning
(“mushroom”) which in turn is derived from
the Greek word ‘sphongos’ to describe
eukaryotic organisms that are spore-bearing,
have absorptive nutrition, lack chlorophyll,
and reproduce both sexually and asexually.
• The study of fungi is called as mycology.
• The person who studies about fungi are
called as mycologists.
• The study of fungal toxins and their effects is called as
• The diseases called by fungi in animals are called as mycoses.
• Fungus is a member of large group of eukaryotic
organisms that includes microorganisms such as
yeasts, moulds and mushrooms.
• These organisms comes separately under the
kingdom Fungi, which is separate from plants,
animals, protists and bacteria.
• This is because of the difference in the fungal cell
wall which consists of chitin whereas others
consists of cellulose, peptidoglycan, etc.
• Mycology has often been regarded as a branch of botany, even though
it is a separate kingdom in biological taxonomy.
• Genetic studies have shown that fungi are more closely related to
animals than to plants.
• Three billion years
