1 to 10
Where do flagellate protozoans live?
In aquatic environments
How does ciliate protozoans move and feed?
Celia’s all around the cell
Where do ciliate protozoans live?
Aquatic environments
What is the most complex protozoan?
Paramecium
how do pseudopodia protozoans move
Through pseudopods
what does amoeba mean?
Changing shapes
how do you pseudopodia protozoans move?
The cytoplasm pushes, I am changes the shape of amoebas to create new arms and feet that engulf the food
what two diseases does amoeba cause
Dysentery and brain eating
How do you sporozoan protozoans move?
They can’t move unless they are in a vector
How does Borazon proud of zones produce and reproduce?
Through spores
What is both autotrophic and head trophic?
Euglena
When is Euglena autotrophic?
When it is plant like it is in the sun and it is photosynthesis
when is Euglena heterotrophic
When there’s no sun, and it is animal like and it is a flageolet, and it is is flagella
What is plant like protist?
algae
Are algae, unicellular or multicellular
Both but mainly unicellular
What is the basis of aquatic food webs?
Algae
How much oxygen does algae produce
1/2 of the oxygen on the earth
How is algae classified?
By the color of the wave length of light that is absorbed
do all LG have chloroplasts
Yes
what are the three types of algae?
Green, algae, brown, algae, red algae
what is green algae?
The most common, the most diverse, the ancestor of green plants
what type of algae is Volvox and Spyrogyra?
Green algae
what is the largest type of algae
Brown algae
What is brown algae made out of
thallus- main body
holdfast- attaches to the floor
airbladders- to float
How does brown algae absorb water
Through osmosis
What is red algae?
Similar to seaweed, also called red tide, found in oceans, usually toxic
Why are they funguslike?
Because they are hydrophobic decomposers
what are the three types of funguslike protists?
Slime, molds, water, mold, downy mildew
What does funguslike protist do?
Breaks down dead material into usable material
Where does fungus like protist live and what do they feed on?
they live in cold, wet areas and feed on riding leaves or stumps
During unfavorable conditions and amoeba forms
a cyst
Are Euglena multicellular or unicellular?
Unicellular
What organelle does photosynthesis
Chloroplast
What end as a flagellum located?
The front
What are two ways Euglena get their nutrients
Through photosynthesis and absorbing through the cell membrane
what is the function of the contract tile vacuole and what would happen if the cell didn’t have it?
It helps the cell remove excess water, and the cell would explode without it
is the paramecium unicellular or multicellular
Unicellular
why can’t a paramecium change shape
It has a pellicle
What does the macro nucleus do?
Respiration, proteins, synthesis, and digestion
What does the micro nucleus do?
Reproduction
What is the oral groove?
The intended area where food enters the paramecium
waste exits, the paramecium, through what structure
The anal poor
what is the function of Trichicyst
To entangle a predator or make themselves look bigger
what is the difference between ectoplasm and endoplasm
Ectoplasm is clear and endoplasm is dense
what is avoidance behavior?
When do paramecium moves away from negative or unpleasant stimulus?
Where do paramecium’s live?
And quiet ponds
what classification of Proto zones is the amoeba
psedopodia
what classifications of the Proto zone is Euglena?
Flagellate
what classification of protozoans is the paramecium?
cilliate
how many fungus are heterotrophic decomposers
All
How many fungus are eukaryotic?
all 
What are fungus cell walls made of?
chiten
What do fungus is reproduce with?
Spores
Are all fungi multicellular
No, but Most are
What are three ways that fungi can get their food
Saprophytic, parasitic, symbolic
What does it mean when a fungi is a decomposer or saprophytic?
they change complex materials into waste or dead material into raw material
What does it mean when a fungi is parasitic?
Hostaria, which penetrates Hosell and absorbs nutrients
what does it mean when a fugi is mutualistic or symbiotic?
both organisms benefit. it absorbs nurtients from the host plant or algai but retains watger and minerals from the soil around it.
what is a fungi cell wall made of
chitten
what is another name for club fingi
basidiomycota
whats an example of basidiomycota
edible mushrooms, puffballs, bracket fungi
where are pores produced in club fungi
in a mushroom cap that contains basidia
how many types of fungi are there
3
what is another work for bread molds
zygomycota
what are the 3 types of hyphae
rhizoids, stolons, sporangia
what do rhizoids do
1st to grow, grow downwards, get food/ nutrients to grow
what do stolons do
grow horazontaly away from rhizoids, spread mold
what do sporangia do
grow upwards, makes spores
what are examples of sac fungi
morel mushrooms, and yeast
where are spores produced in sac fungi
in sacs, not basidia
what kind of medicine is derived from fungi enzymes
penicillin
