! Eukaryotic, heterotrophic, have cell walls made of chitin
! All multicellular, except for yeasts ! Feed by digesting food outside their body
and then absorbing it ! Most reproduce sexually and asexually
" Asexual – cells break off and begin to grow on their own
" Sexual – involves 2 different mating types
! Based on method of reproduction and their structure
! 4 main groups: " Common molds " Sac fungi " Club fungi " Imperfect fungi
! Recycle nutrients through the ecosystem ! Break down dead / decaying matter ! Parasitic – cause human and plant diseases
" Exp: athletes foot
! Symbiotic relationships " Lichens – algae and fungus " Mycorrhizal – fungus and plant roots
