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 Protozoa

a. Unicell (mono cell)

b. Size 100-3000 micron

c. Euchariotic (has nucleus membrane)

d. Life with soliter (individual) and coloni (group)

e. Heterotrof and there are Autotrof in common

f. 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 water

Example : 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 thread

Heterotrof and absorbtif

Sometimes has flagel cells in their life

Cell 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 : Dictyosteliumdiscoideum

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)

Disadvantages

Cause many disease in human, example:

malaria disease→ Plasmodium sp.

sleep disease → Trypanosoma gambiense

disentri disease → Entamoeba histolytica

Useful of Myxomycophita

Advantages

as decomposer

as 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!
