3. Define mycology, mycoses
Mycology
is the Study of Fungi
Mycoses
It is an infection caused by any fungi that invade tissues,
causing a superficial, subcutaneous, or organ disease.

4. Importance of fungi - harmful ,
useful fungi
• Some fungi can
cause diseases in
humans and animals
• Fungi can cause
plant diseases
• Some fungi cause
foodstuff to spoil.
Harmful fungi
• fungi decompose dead
organisms (particularly
plants) and recycle their
nutrients.
• Fungi are used in the
production of bread and
alcoholic drinks and some
kinds of cheese.

5. • Fungus cell contains a true
membrane-bound nucleus.
• Fungi have membrane-
bound organelles
• Fungi have a rigid cell wall
• Fungal cell wall contain chitin

7. Heterotrophic absorptivenutrition
• Fungi lack chlorophyll and do
not perform photosynthesis.
• Fungi are Heterotrophs. They
use organic compounds as
carbon source.
• Plants are autotrophs. They
use CO2 as carbon source
describes a way of obtaining
energy and nutrients in which
digestive enzymes are secreted
into a substrate, then smaller,
easily assimilated molecules are
absorbed through the cell
membrane.
Heterotrophic and absorptive nutrition of fungi

8. Classification of fungi
Fungi can be:
1. Saprophytic: decompose dead organic
matter.
2. Parasitic: feed on living hosts (causing
disease).
3. Mutualistic symbiotic: Obtaining their
nutrients
from a living host while providing some benefit to
that host

9. Fungal Morphology
• Fungi grow in
two basic
morphological
forms:
• Molds
• Yeasts
(Budding fungi)
• Dimorphic (can
switch between
yeast and mold
forms).
”
Molds
• Growth in the mold form
occurs by
production of Hyphae.
• Hyphae are long tubular
branching
filaments of fungal cells .
• The mass of intertwined
hyphae that
accumulates during active
growth is a
mycelium.
Yeasts
• Unicellular fungi.
• Usually spherical or
oval in shape.
• Most yeasts
reproduce by
budding.

10. Reliability
septa: In some fungi,
hyphae
are partitioned into cells
by cross walls

Hyphae and Septa

11. • Molds reproduce by producing large
numbers spores.
• Spores can be produced either from
asexual or sexual reproduction.

12. • Yeast usually
reproduce asexually
