WEEK 6 Flashcards
PROTOZOA AND SLIME MOLDS
what are protozoans
first animal
most versatile of all EUKARYOTES
characteristics of protozoans
heterotrophic
have food vacuoles to enclose food particles for digestion
contractile vacuoles to expel excess water
reproduction of protozoans
sexual, genetically diff offspring
and asexual == clones
protists and there BOTH types of sexual rep how often
asexual - routinely
sexual intermittently
conjugation also possible
3 examples of protazoans
Amoeba, Trypanosoma, and Malaria
Whats an amoeba
type of protozoan that is very flexible and has pseudopodia
Where is Amoebas found
arine, freshwater, and teresstrial environments
What are psudopods
they are movable extensions of cytoplasms that act as invisble feet, help move
What are trypansoma
pathogenic type of protozoan that are found in tropics
what diseases do trypanosoma cause
African sleeping sickness = cause testes fly Chagas disease = assasin bug
What is Malaria
another type of disease that is caused by mosquitos that transfer PLASMODIUM
Slime molds
AMOEBOZOA
protists, decomposers
What are Saprophytes
types of fungi that live by digesting dead plants
4 types of fungi according to how they sex
- CHYTRIDS
- BREAD MOLD
- SAC FUNGI
- CLUB FUNGI (BASIDIOMYCOTA)
WHERE DO CHYTRIDS live
CHYTRIDOMYCOTA
aquatic freshawater
can chytrids move
yes have motile cells
whats dangerous about chytrid fungus
lead to amphibian population decline
what is an example of BREAD MOLD
zygomcyta
rhizopus tolonifer (black bread old)
where is black bread mold found
decaying bread and fruit
2 SAC FUNGI
LICHENS AND PCN producing fungi
lichens
primary food source for animals and make soils
with who do sac fungi (asycomycota) have symbiotic relationships with)
cyanobacteria
sac fungi
PCN PRODUCING FUNGI
PRODUCE PENNICILIN ROLE IN ANTIBIOTICS
CLUB FUNGI
basidiomycota
MUSHROOMS, PUFFBALLS, FELF FUNGI, RUSTS, SMUTS
