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.

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.

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
