KINGDOM FUNGI

PRESENTED BY PRAJINA.P B.Ed NATURAL SCIENCE ROLL NO: 05 ZAINAB MEMORIAL COLLEGE OF TEACHER EDUCATION CENTER KASARAGOD , KERALA

Study of fungi : MYCOLOGY Cell wall : chitin & polysaccharide Heterotrophic organism Fungi are cosmopolitan (found every where) They prefer to grow in warm & humid place Multicellular eukaryotes (except yeast)

Unicellular Used for making bread &Beer Eg : Saccaromyces cerevsiae ( baker’s yeast) Puccnia triticina – wheat leaf rust(pathogenic) Pencillium sp . -- antibiotics YEAST

BODY ORGANISATION Filamentous body Long slender thread like structure – HYPHAE Network of hyphae -- MYCELIUM Mushroom are a FRUITING BODY

HYPHAE Septate Aseptate/ coenocytic (cross wall present) (cross wall absent)

MODE OF NUTRITION Saprophytic Parasitic Symbiotic

Eg : SYMBIOTICE ASSOCIATION FUNGI + ALGAE ( Mycobiont ) ( Phycobiont ) FUNGI + ROOTS MYCORRHIZA LICHEN

REPRODUCTION VEGETATIVE REPRODUCTION ASEXUAL REPRODUCTION SEXUAL REPRODUCTION .FRAGMENTATION 2.FISSION 3.BUDDING ASEXUAL SPORES: CONIDIUM SPORANGIOSPOR ZOOSPORE: 1.BASIDIOSPORE 2.ASCOSPORE 3. OOSPORE

KINGDOM FUNGI classification PHYCOMYCETES ASCOMYCETES BASIDIOMYCETES DEUTEROMYCETES

USEFUL FUNGI Important source of food. eg : Morchella & Agaricus (edible) Important in bakeries ( making bread) Important in breweries (making alcohol) Yeast also produce vitamin B Good decomposers Production of antibiotics – Pencillin ( Pencillium notatum )

Penicillium notatum yeast AGARICUS MORCHELLA

HARMFUL FUNGI Moulds are responsible for the spoilage of food, leather goods and textiles Fungi attack crops, cause huge loss to farmers It cause serious skin and lung infection in human beings (Athlete’s foot and ringworm are some common fungal infection)

POISONUS FUNGUS RINGWORM ATHLET’S FOOT

SEXUAL CYCLE INVOLVES : PLASMOGAMY: fusion of protoplasm between two motile/two non-motile KARYOGAMY: Fusion of nuclei Meiosis in Zygot results Haploid Spore(n) DIKARYON : n+n condition ,such phase is called Dikaryotic phase Eg:ascomycetes and basidiomycetes
