KINGDOM PROTISTA
ANIMAL-LIKE PROTISTS
ZOOPLANKTON
4 PHYLA:1. Sarcodina (Amoeba)
2. Ciliophora (Paramecium) 3. Sporozoa (Plasmodium)
4. Mastigophora / Zoomastigina (Trichonympha & Trypanosomiasis)
Sarcodina(Amoeba)
Phylum SarcodinaReproduction: asexual
Locomotion: pseudopods (false feet)Movement occurs by cytoplasmic
streaming extensions or projections of cytoplasm (projections = pseudopods)
Nutrition: phagocytosis – heterotrophs
Other information: Cytoplasmic streaming
Example: Amoeba
AMOEBA FEEDING
Ciliophora (Paramecium)
Phylum CiliophoraReproduction: asexual &
sexual
Locomotion: cilia
Nutrition: Cilia used to sweep food into “mouth” – heterotrophs
Other information: Trichocysts – for defense
Example: Paramecium
Phylum Ciliophora: PARAMECIUM
2 NucleiMacronucleus
controls cell activitiesMicronucleus is
involved in reproduction
Sporozoa(Plasmodium)
Phylum SporozoaReproduction: Asexual & sexual
(spores)
Locomotion: Non motile = rely on vector or body fluids of host of movement
Nutrition: All parasitic – heterotrophs
Other information: Need host for nutrition
Example: Plasmodium
PLASMODIUM LIFE CYCLEVectors (mosquitos)
transmit plasmodium from 1 host to another – the only
way plasmodium can moveCauses malaria in humans –
humans are the hostHave a spore-like stage in
life cycle
Do not copy
Mastigophora / Zoomastigina(Trichonympha & Trypanosomiasis)
Mastigophora / Zoomastigina• Reproduction: asexual• Locomotion: Flagella• Nutrition:
Heterotrophs – most are parasites
• Other information: cause disease in humans
• Examples: Trichonympha & Trypanosomiasis
Kingdom Protista Drawings
2. Paramecium– Draw a labelled
diagram of Paramecium
– Label: macronucleus, micronucleus, food vacuole, contractile vacuole, cilia, trichocysts and gullet
Kingdom Protista Drawings3. Amoeba• Draw a labelled diagram of an amoeba• Label: pseudopod, food vacuole, nucleus and contractile
vacuole• What is the function of each part?• Explain the following terms: ectoplasm, endoplasm,
phagocytosis and cytoplasmic streaming
