3 Protista Classification: Animal-like = Protozoa Plant-like = Algae
Fungus-like = Moulds All live in aqueous / moist environments

4 PROTOZOA Phyla for protozoa are based on type of locomotion / mobility
Common Name Proper Phyla Name Example Protozoa Flagellates Zoomastigina Trypanosoma Sarcodines Sarcodina Amoeba Ciliates Ciliophora Paramecium Sporozoans Sporozoa Plasmodium

5 Flagellates / Zoomastigina
Has one or more flagella Has hard, protective covering Freeliving, parasitic and symbiotic  Ex. Trypanosoma – African Sleeping Sickness Human parasite

6 Sarcodines / Sarcodina
Have pseudopodia Mostly live in animal intestines A few parasites, free-living Example: Amoeba Pseudopodia allows it to move and engulf prey Have ectoplasm and endoplasm Feed via phagocytosis Reproduction by binary fission

7 Ciliates / ciliophora Has cilia (hair-like structures)
Free-living, symbiosis, parasites 2 nuclei One for macro controls – cell activities One for micro controls – reproduction

8 Sporozoans / Sporozoa No flagella, cilia or pseudopodia
Generally parasites Have few organelles and specialized structures Complex life cycles Reproduce without fertilization (ex. Spores)

9 ALGAE ( Plant-like protists)
Protists that contain chlorophyll Lack the leaves, stems, roots and water-conducting tissues Algae are classified into six phyla, based on the type of chroloplasts and pigments they have

10 Phylum: Chlorophytes -Autotrophs
-Pigments: chlorophyll a and b, carotenoids -Live in fresh water, some in moist soils and costal tropical seas -Some are unicellular and some are multicellular Examples: Green Algae, Spirogyra, Volvox

11 Phylum: Phaeophytes -Autotrophs
-Pigments: chlorophyll a and c, carotenoid, fucoxanthin -Live in colder seawater Examples: Brown Algae, Kelp, Rockweed

12 Phylum: Rhodophyta -Autotrophs
-Pigments: chlorophyll a, carotenoids, phycobilin -Some live in fresh water, but mostly in warmers sea water Example: Red Algae

13 Phylum: Chrysophyta -Autotrophs
-Pigments: chrolophyll a and c, carotenoids -Live in fresh and salt water -Diatoms are generally unicellular -Diatoms are a major source of oxygen -Diatoms are the biggest component of plankton Example: Golden-Brown Algae, Diatoms

14 Phylum: Pyrophyta -Autotrophs
-Pigments: chlorophyll a and c, carotenoids -Unicellular -Major component of oceanic phytoplankton Example :

15 Phylum: Euglenophyta -Autotrophs or heterotroph
-Pigments: chlorophyll a and c, carotenoid -Half of them do not have chloroplasts -Unicellular -Live in fresh water Example : Euglena

16 MOULD – Fungus-like Slime Mould Water Mould
Difficult to classify because they are like: Protozoa since they glide Plants since they have cellulose cell wall Fungi since they produce spores

17 Here’s the Breakdown: Phyla: Oomycota Phyla: Myxomycota
Water PROTISTA Slime Phyla: Myxomycota Phyla: Acrasiomycota

18 Phylum: Oomycota -Saprotrophs -Some are parasites 175 species
Example: Water mould

19 Phylum: Myxomycota -Slug-like organisms -Contain many nuclei
-Feed by engulfing -Spores are produced during sexual reproduction -560 species Example: Plasmodial slime moulds

20 Phylum: Acrasiomycota
-Exists as individual amoeboild cells with 1 nucleus -Feed by ingesting yeast, bacteria -65 species Example: Cellular slime moulds
