The document summarizes the three major kingdoms of protista - protozoa, algae, and fungus-like protists. Protozoa are animal-like single-celled eukaryotes that can move and are heterotrophs. Examples include amoebas, zooflagellates, ciliates, foraminiferans, and apicomplexans. Algae are plant-like protists that can photosynthesize and include euglenoids, dinoflagellates, diatoms, brown algae, red algae, and green algae. Fungus-like protists are slime molds and water molds.

1. Kingdom protista
Chapter 7

2. Major groups of protista
 Protozoa: animal like protest
 Algae : plant like protest
 Fungus like protest : slime molds and water molds

3. Protozoa : animal like protist  Animal-like Protists. Animal-like
protists are called protozoa. Protozoa
are single-celled eukaryotes that
share some traits with animals. Like
animals, they can move, and they are
heterotrophs
1. Amoeba
2. Zooflagellates
3. Cilliats
4. Foraminiferans and actinipods
5. apicomplexans

4. 1. Amoeba
• Pelomyxa palustris also called as The
giant amoeba (takes energy from
methanogenic bacteria)
• Entamoeba histolytica ( it causes
dysentery in humans )

5. Zooflagellates
• Trichonymphas
• Trypanosoma
• Choanoflagellates

6. Cilliates
1: Paramecium ( motile ciliate )
2: Stentor (sessile ciliate)

7. Foraminiferans
Actinopods
Examples
1. Forams (foraminiferans)
2. Radiolarians ( actinopod)

8. Apicomlexans
Example Plasmodium
( it causes malaria)
Stages
• Sporozoites
• Merozoites
• Ring stage
• Gametocytes
• Egg and sperm
• Zygote

9. Algae ( plant like protist)
• Euglenoids
• Dinoflagellates
• Diatoms
• Brown algae
• Red algae
• Green algae

10. Euglenoids
It behaves both autotrophically as well as
hetrotrophically

11. Dinoflagellates
2nd major group of protist
Involves in the formation of red tides

12. Diatoms
Major producers in aquatic (marine and fresh
water) life.
Play important role in marine food chains
They have beautiful patterns and contains
two shells

13. Brown algae
kelps ( largest brown algae)
Example: laminaria

14. Red algae
Helps in formation of coral reefs along with
coral animals
Example : Polysiphonia

15. Green algae
• Chlamydomonas (
unicellular)
• Dermids ( two cells with two
halves)
• Volvox ( colonial )
• Spirogyra ( filamentous )
• Ulva ( sheet like )
• Chlorella

16. Chlamydomonas

17. Dermids

18. Spirogyra

19. Volvox

20. Ulva
It has sheet like body and also called as sea
lettuce

21. Chlorella
It has all the essential nutrients that human
body needs and also very important for
research use
