(a) Mode of nutrition
• Phycomycetes are obligate parasites or saprophytes.
• Ascomycetes are saprophytes or parasites or coprophilous.
• Basidiomycetes are saprophytes or parasites.
• Deuteromycetes are manly saprophytes, some are parasites.
(b) Mode of reproduction
• In phycomycetes, asexual reproduction is by zoospores (motile) or by aplanospores.
• In ascomycetes, asexual spores (conidia) and sexual spores (ascospores) are produced.
• In basidiomycetes, vegetative reproduction takes place by fragmentation. Plsamogamy is also seen.
• In deuteromycetes, only vegetative reproduction is seen.
