Protozoans : Animal-Like Protists

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.

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
