Cell walls composed of chitin: a strong flexible
polysacchride
Hyphae are the basic structural filament units
that make up the body of multicellular fungi
Mycelium is a netlike mass of hyphae found
below ground
Fruiting Body is the reproductive structure
found above ground
Septa are the cross walls that divide the hyphae
into cells, these allow nutrients, cytoplasm,
organelles, and nuclei to flow between cells


Saprophytic Fungi
 Saprobe is an organism that
feeds on dead organisms or
organic wastes
 Decomposers and recycle
nutrients back into the food
web
 Parasitic
 Absorb

Fungi
nutrients from living cells
or another organism called a host
 Produce hyphae called haustoria
which grow into the host tissue
Arthrobotrys are parasitic soil fungi
that trap prey with rings of hyphae

Mutualistic Fungi



Live in combination with another
organism for the benefit of both
organisms
Plant or algae
Mycelia covers the roots of the soybean
plant and absorbs sugar from the plant
and increases water uptake and mineral
absorption for the host plant
 Budding
 Asexual
Resproduction
 Yeast cell
 New cell develops attached
to parent cell then pinches
off

Fragmentation
 Occurs when the mycelium of
a fungus is physically broken
 If the broken fragment lands
in a location suitable for
growing hyphae will grow
into new mycelia

Spore Production
 Most fungi able to reproduce sexually and
asexually by producing spores
 Spores a haploid reproductive cell with a
hard outer coat
 Spores develop into new organism without
the fusion of gametes
 Spore generates haploid hyphae and fuse
with hyphae of another to become diploid
 Diploid produce fruiting bodies that will
produce zygotes that go through meiosis to
produce haploid spores




Produces large quantities of spores, small and
light weight
Spores protected by a cell wall, tough and
water proof
Sporophores are the fruiting bodies of a sporeforming fungus
Sporangium is a sac or case in which spores are
produced, provide protection
