Lichens
of Zygomycota ASEXUAL REPRODUCTION: SPORANGIA FORM AT THE TIPS OF SPORANGIO- PHORES. THE SPORANGIA PRODUCE SPORES THAT ARE DISPERSED BY WIND.
of Zygomycota SEXUAL REPRODUCTION IS CALLED CONJUGATION. 2 MATING STRAINS JOIN AND FORM A ZYGOSPORE. MEIOSIS OCCURS WHEN SPRORE GERMINATES.
ASEXUAL REPRODUCTION: CONIDIA (SPORES) ARE FORMED ON THE ENDS OF CONIDIOPHORES. YEASTS: BUDDING of Ascomycota
THE REPRODUCTIVE BODY IS CALLED AN ASCOCARP. SACS CALLED ASCI FORM ON THE SURFACE OF THE ASCOCARP. EACH ASCUS CONTAINS 8 HAPLOID ASCOSPORES. of Ascomycota
ASEXUAL REPRODUCTION IS CALLED FRAGMENTATION. THIS FORM OF REPRODUCTION IS RARE IN THIS GROUP, EXCEPT IN SOME RUSTS AND SMUTS. of Basidomycota
THE REPRODUCTIVE BODY IS CALLED A BASIDIOCARP. THE UNDERSIDE OF THE MUSHROOM CAP IS LINED WITH GILLS. CLUB SHAPED REPRODUCTIVE CELLS CALLED BASIDIA FORM ON THE GILLS. THE BASIDIA PRODUCES BASIDIOSPORES & RELEASE THEM WHEN CONDITIONS ARE FAVORABLE.
ASEXUAL REPRODUCTION: CONIDIA (SPORES) ARE FORMED ON THE ENDS OF CONIDIOPHORES. of Dueteromycota
FUNGI IN WHICH SEXUAL REPRODUCTION HAS NOT BEEN OBSERVED of Dueteromycota
