What is a fungus?
1.Eukaryotes
2.Use spores to
reproduce
3.Heterotrophs
Where Do Fungus Grow?
• Damp, warm areas like dewy lawns,
bathroom tiles, moist foods, damp tree
barks, etc…
The Fungus Cell Structure
• Yeasts are
unicellular
• However, all other
fungus have
structures called
HYPHAE.
What are HYPHAE?
• Hyphae: branching,
thread-like tubes
that make up the
body of multi-cellular
fungi
How the hyphae are arranged
determine what the fungus will look
like loosely tangled or tightly packed
• Contain many nuclei;
substances move
quickly through the
hyphae
Parts of
a Fungus
Fungus use Hyphae to Obtain Food
•
•
Fungus grows hyphae into its food source
Digestive chemicals ooze from the hyphae and
break down the food into small substances
Fungi Reproduce Asexually
and Sexually
ASEXUAL REPRODUCTION 1. Yeasts reproduce asexually
by budding. A small yeast
cell grows from a larger
parent cell.
2. When the conditions are
right, fungi will grow fruiting
Budding yeast cell
bodies (reproductive
structures) that release
spores.
Fungi Asexual Reproduction
•
•
•
Puffball and its spores.
•
Fungi reproduce by
producing light-weight
spores. A tiny cell that is
able to grow into a new
organism.
Spores are carried through
the air or water
Fungi OVERPRODUCE their
spores because only a few
will fall where conditions
are favorable.
Spores are produced in
fruiting bodies.
Fungus Reproduce
Sexually
• When the conditions
are not optimal for
asexual
reproduction, fungi
may reproduce
sexually. Two
hyphae grow and
genetic material is
exchanged.
Sexual Reproduction in
bread mold fungus.
How are Fungus
Classified?
Puffball
Mushroom
releasing spores.
• Fungus are classified
into groups based on
the shapes of their
spore-producing
structures and their
ability to reproduce
sexually. They are
classified into three
groups.
Classifications of Fungus
Sac-like
Fungi
(Morels)
Zygote Fungi
(Rhizopus)
Club Fungi
(Geaster – puffball)
The Role of Fungus in Nature
1. Food
2. Decomposers and
Recyclers
3. Cure Disease
4. Cause Disease
5. Live in Symbiosis
with other
organisms
Role of Fungi in Nature
1. Help make food
products.
a. Breads
b. Cheeses
c. Beers and wine
2. Break down
the chemicals
in dead
organisms.
Benefits of Fungi
3. In 1928 Alexander Fleming discovered Penicillin, a
blue-green mold that kills bacteria. It is used as an
antibiotic.
•Fleming discovered penicillin by accident. He was
growing samples of bacteria and noticed that a spot
of mold was stopping the bacteria growth.
Harmful Fungi
4. Some fungus can
cause damage to
crops or cause
diseases in humans
as well.

Athlete’s foot
Ringworm
Plant Rusts

Fungus Working with Other Organisms
5. Some fungus grow in
the roots of plants
and help them grow
larger and healthier.
The hyphae of the
fungus absorb water
for the plants and
the fungus gets
food.

What are Lichen?
Made up of a fungus
and either an
algae/bacteria
Fungus gets food
made by the algae
Algae gets nutrients
from the fungus.
Sensitive to pollution
scientists watch
lichen to see if the
air is clean in an
area
