•Cattle, like other some other animals such as goats, deer, and
giraffes, have billions of microbes inside their guts which help
them digest their food
•The large microbe is a type of protist.
•The creature that looks like a tadpole attached to the side of the
protist is a fungal spore.
•The smaller, rod-shaped beasts lining the underside of the protist
are bacteria.
Associations between fungi and
plants
•Mycorrhizae are
symbiotic
relationships
between fungi
and plant roots
(the term means
literally 'fungus
root').
•Perhaps more
than 80% of the
species of higher
plants have
these
relationships

Lichens
• Mutualistic
relationship
between a
fungus and an
algae (or a
photosynthetic
bacteria).

•Some species are predatory fungi that live in the soil
and ensnare animals such as nematodes
(roundworms) in a loop of hyphae.
•Human-Athletes foot, ringworm

Each spore has the
potential to generate
another individual of
the species.
• Spores can be spread out
(dispersed) by wind, water, &
animals.

Usefulness of Fungi
•Fungi are valuable economically as a
•Antibiotics, vitamins
•various industrially important chemicals, such as
•Acetone, Enzymes
•fermentation processes, as in the production of
•alcoholic beverages, vinegar, cheese, bread dough
•Extremely important in soil renewal, through
the decomposition of organic matter

Yeasts
•single cells, produce
daughter cells either
by budding or by
binary fission
•the common baker's
yeast- Saccharomyces
cerevisiae

Fairy Rings
The mycelium grows in a circle and mushrooms
grow on the edges of the mycelium, so the
mushrooms grow in a circle!
