Walls
Made of Chitin
Same substance that arthropods use for their
exoskeletons
 Heterotrophs



No Chloroplast so they have to consume others
They either live next to, on or in their food
They are either decomposers, parasites or live in
mutualism with another organism

When a fungus lives in the roots of plants helping the
plant to get nutrients and getting food back it is called
a mycorrhiza
 Secret



Lives
Majority of a fungus lives below the surface
either the dirt or the organism it is on
Their cells are grouped in chains called Hyphae
Hyphae usually grow close to each other in a
tangle called mycelium
 Spores

Fungi can reproduce asexually and sexually
 Asexual


Broken pieces can grow into new fungi
Can send out spores that wait until right
conditions to grow
 Sexual

Reproduction in Fungi
Reproduction in Fungi
Grow structures that send out Sexual spores,
they fertilize and then grow when the conditions
are right
 Fungi


are classified based
Shape
How they reproduce
 Threadlike

Fungi
Parts of the hyphae

ground
How they reproduce


Asexually: form
sporangia that
releases spores
Sexually: two hyphae
meet form different
sporangia

Asexually: Most of the
time, Yeast do
budding leaving scars
Sexually: Form sacs
called ascus

(mostly)
Animalia


Defined more by
what they are not,
than what they are.
Protista have only
two traits that they
all share; Eukaryotic,
and no specialized
tissue
Have Chloroplasts
 Undergo
Photosynthesis
 Autotroph (self-feed)

Producer
Some are consumers
like animals
 Decomposers
 Parasites feeding on a
Host
 Heterotroph(different
feed)


Reproduction
Divide the parent cell to make identical offspring
Called “fission”
Binary fission makes two copies
Multiple fission more than two copies
 Sexual

Reproduction
No set pattern
 Reproductive



Cycles
Protist reproduces after significant events
Lots of variety
Example: Protist lives in one form in mosquito is
transferred to a host where it reproduces into
another form, then transferred back to a
mosquito
 Broken

down into three groups
Protist Producers
Heterotrophs that can move
Heterotrophs that can’t move
 Red
Algae
Producer
 Chlorophyll with red
pigment
 Most common
seaweed – grows in
the Tropics at deep
depths

 Green

Chlorophyll
Most Diverse group
of Protist Producers
 Brown




Algae
Producer
Chlorophyll with
yellow brown
pigment
Seaweed in cooler
climates
Can grow up to 60
m in one growing
season
 Diatoms
Producer
 Chlorophyll
 Large portion of
Phytoplankton
 Have 2-part glass
like shell made of
Silica
 Come in various
shapes

 Dinoflagellates

Producer Sometimes
Chlorophyll –
Sometimes
Some live in fresh
water, some Salt
water, some in
SNOW!
Have two flagella
 Euglenoids




Producer sometimes
Chlorophyll –
sometimes
When food is scarce
all of them become
heterotrophs
Live in freshwater
and move with a
flagella
 Amoebas
Consumer or
Parasites
 Fresh and salt water
 Move using
pseudopodia (false
feet)

 Shelled
Amoeba-
Like
Consumer
 Fresh and salt water
 Have an outer shell
 Poke psuedopod out
of pores in the shell

 Zooflagellates


Consumer or
Parasites
Move by waving
flagella back and
forth
 Cilliates



Consumer
Thousands of
Cilia(hair-like
structures)
Cilia push food
toward the mouth
and make it swim
 Spore-Forming
Protist
Consumer Many
parasites
 No Cilia/Flagella
 Have complicated
life-cycles (2 hosts
usually)


Molds
Consumer some
decomposers most
parasites
 Slime

Molds
Consumer
Can move in some life
stages
Grow as long as food
and water is available
Some become large
cells with many nuclei
up to 1 m across
Reproduce by growing
stalks that release
spores
Is a combination of
fungus and algae
 Alga lives inside the
fungus


Such a close and
dependant life cycle
that they are considered
one organism
Producers
 Fungi cell walls
protect alga and keep
in water
 Very sensitive to air
pollution
