of Basidomycota

of Basidomycota• THE REPRODUCTIVE

BODY IS CALLED A BASIDIOCARP.

• THE UNDERSIDE OF THE MUSHROOM CAP IS LINED WITH GILLS.

FOUND IN SOIL & DUNG

• INCLUDES THE BLACK BREAD MOLDS

• ZYGOMYCETES ARE COENOCYTIC (HYPHAE LACK SEPTA)

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.
