What is the Latin word from which ‘fungus’ is derived?
Fungous
What is the study of fungi?
Mycology
General characteristics of fungi
- Ubiquitous
- Heterotrophic
- Eukaryotes (with one or multi nuclei)
- Cosmopolitan distribution
- Microscopic or macroscopic sporocarps
- Sexual or parasexual reproduction
- Simple or complex life cycle
What is sexual reproduction in fungi?
It is usually nuclear fusion or meiosis
What is parasexual reproduction in fungi?
It involves nuclear fusion, followed by a gradual de-diploidization and/or asexual (pure mitotic nuclear) division.
Who classified living things into plants and animals?
Karl Von Linne, 1735
Who divided living things into kingdoms?
Whittaker, 1969
What were earlier systems of classification based on?
- Thallus organization and cell wall
- Life cycle pattern
- Type of asexual pores
- Presence and absence of sexual reproduction and its type
On what basis are recent systems of classification?
Physiology
BIochemistry
Serology
Morphology
Scientists who classified fungi…
Bauhin 1623 Gwyne-Vaughan and Barnes, 1926 Gauman and Dodge, 1928 Bessey, 1950 Martin, 1961 Alexopoulus and Mims, 1979 Ainsworth, 1966, 1971, 1973 Hawksworth et al 1985, 1995
On what basis did Ainsworth classify fungi?
Morphology, especially of reproductive structures.
Under what kingdom did AInsworth classify fungi?
Mycota, with slime molds.
Characteristics of kingdom Mycota
- No chlorophyll II
- Free-living, parasitic or mutualistic
- Variable cell wall composition (chitin and glucan)
- Reserve food material are oil, manitol and glycogen
General characteristics of Division Myxomycota
- Plasmodium or pseudoplasmodium present
- Slimy
- Called false fungi
