Unit 6 – Lecture 2
Protists – General Char.most diverse of any kingdom
unicellular or multicellularmicroscopic or macroscopicheterotroph or autotrophasexual or sexual reproduction
all are eukaryoticmost live in water
Protists – General Char.divided into sub-sections:
animal-like protists: protozoansplant-like protists [algae]fungus-like protists
Some of the most harmful and beneficial orgs.
Protozoansanimal-like protistsunicellularheterotrophicmainly asexual
reproduction
Protozoansphyla are grouped by their method of
movementciliophorazoomastiginapseudopods sporozoa
Ciliophoraciliatessexual or asexual
reproductionalmost all benignex: paramecium
Zoomastiginaflagellates parasitic or
beneficialflagellate in

sleeping sickness
DiscussWhat is the term collectively
for all animal-like protists?
How are all animal-like protists grouped?
Organisms which move using cilia are in the phylum…?
Organisms which use flagella to move are in the phylum…?
Pseudopodsphylum name: rhizopoda or sarcodinashapeless, no cell wallmost live in salt waterasexual reproductionex: amoeba
Pseudopodsingest food via phagocytosis
literally, cell eatingingest water by pinocytosis
literally, cell drinkingcauses amoebiasis –
Montezuma’s Revenge – diarrhea, intense abdominal pain, dehydration
white blood cells are NOT pseudopods –
the image is to show phagocytosis.
Sporozoamost produce sporesnon-motile almost ALL
are harmful
Sporozoaex: P. falciparum – causes malaria – destroys
blood cells, chills, fever, fatigue, death.ex: Toxoplasmosis – harmless to most adults,
but can cause infant blindness, mental retardation, other deformaties
DiscussWhat are the four phyla of protozoans by
their…phylum names?method of movement?
Which phylum of protozoans contains organisms which are almost ALL parasitic?
What are the two major functions of pseudopodia?
Odd Orgs Out: EuglenophytaEuglena
not an animal-like protist, buthas animal- and plant- like characteristics
flagellumanimal-like –
may take in food
plant-like – photosynthetic
