Basic Competency
Describing the characteristics of phyla in Protists and their role in life
Indicator
Describing the characteristics of Protists
Distinguish among fungi-like, plants-like, and animal like Protist
Explain the basic classification like of fungi like, plants-like, and animal-like Protists
What’s this picture?
Characteristics of Protozoaa. Unicell (mono cell)b. Size 100-3000 micronc. Euchariotic (has nucleus membrane)d. Life with soliter (individual) and coloni (group)e. Heterotrof and there are Autotrof in commonf. Free life (Cosmopholit)g. Move with rhizopodes, flagella, and cilia.
h. Vegetative reproduction with self division and shape of bud with Generative reproduction with conjugation
Classification of Protozoa
1. Rhizopod Has move tools is pseudopod (false
foot) Life Style : parasite and free Habitat: sea and water Example: Amoeba proteus
Flagellata
Has move tool is flagella called whip feathers
Life Style with autotrof (Phytoflagellata) and heterotrof (zooflagelata)
Habitat: in the sea and water
Example: Giardia sp.
Ciliates
Has move tools is tremble feathers (cillia)
Life in free area or parasite
Habitat: in the waterExample : Paramecium
caudatum
Sporozoa
Don’t have move tool, but have spore in their life cycle
Usually life in host animal and human
Example: Plasmodium sp.
Characteristics of Fungi like Protists
Structure of body shape filamen or threadHeterotrof and absorbtifSometimes has flagel cells in their lifeCell wall composed from cellulose
(especially water fungi like protists), not from chitin like in fungi
All members can shape spores
Classification of Myxomycophita
1. Myxomycota (mucus fungi plasmodial)
2. Acrasimycota (mucus fungi celluler)
3. Oomycota (water fungi)
Myxomycota ( mucus fungi plasmodial)
Has ± 500 species Habitat: water, damp soil ,
manure of leaf,and collapse stem or plant
Some of members has bright pigment
Not photosynthesis and all members heterotrof
Eating phase has done by amoeboid massa (not flagel) called plasmodium
Sporangium has shape complex. Spores diploid/ haploid depend on condition nucleus in plasmodium
Example :Physarum, Tubifera
Acrasimycota (mucus fungi celluler) Has ± 70 species Habitat: water, damp soil,
manure of leaf,and stem or plant which collapse
Some of members don’t has bright pigment
Move by pseudopod (foot false)
Spread cell from membrane, not soenositik, and haploid organisms
Example : Dictyostelium discoideum
Oomycota (water fungi)
Has ± 580 spesies Saprofit and Parasite Habitat: water, sea and damp
soil Cell wall from cellulose Diploid condition occur in life
cycle oomycota Has flagella cell Different with the other filum
has structure motil (zoospore) spore with 2 flagel
Example: Saprolegnia sp., Phytophthora sp.
Advantages of Protozoa
Useful in food chain as polution indicator Basic material to make brush tool (Radiolaria) as oil indicator(Globerina) help rotten process food residue
(Entamoeba coli)
DisadvantagesCause many disease in human, example:
malaria disease→ Plasmodium sp.
sleep disease → Trypanosoma gambiense
disentri disease → Entamoeba histolytica
Useful of Myxomycophita
Advantages as decomposeras saprofit
Disadvantages Rotten disease in germination plant, example: Phytium
sp. Phytophthora sp. attack potato, coconut, tobacco,
chocolate, kina, and cengkeh plant.
Exercises:
1. How are euglena to similar to both animals and plants?
2. Can you mention all characteristics of class in Protozoa?
3. Mention two ways protists are helpful and two disease caused by protozoa!
