The document discusses the classification of organisms, emphasizing the importance of binomial nomenclature introduced by Carl Linnaeus, which includes genus and species names. It outlines various domains and kingdoms of life, detailing characteristics of organisms such as archaea, eubacteria, and protista, as well as their uses and habitats. Specific groups, including thermophiles and dinoflagellates, are highlighted alongside their biological significance.

15. Kingdom Archaea
• Live in extremely harsh
environments such as:
a. hotspring
b. volcanic vents
c. sewage treatment plants
d. environments with high
salt contents
Thermophiles
Methanogens
Halophiles

16. •This organisms are “Heat –
lover”
• Live in very hot temperature.
- usually in 100 °C
Thermophiles

17. •Are anaerobic archaeans that
releases methane gas
utilized as
BIOGAS
Methanogens

18. • Thrive in extremely salty env’t
such as salt lakes and
evaporating ponds.
• They can withstand 15-30%
salinity of water.
Halophiles

19. Kingdom Eubacteria
• also known as “True bacteria”.
• they are usually unicellular and
microscopic
• their cell wall is made up of
peptidoglycan
• can be found in: a. water b. soil
c. air

20. 3 Types Of Bacteria
According To Shapes.
COCCI
(circle)
BACILLI
(rod-shape)
SPIRILLA
(spiral-shape)

21. 2 Types of Bacteria
according to uses:
1. Non-pathogens (Good Bacteria)
- help in digestion
- they decompose dead cells

22. 2. Pathogens (Bad Bacteria)
- they secrete toxins.
- they cause infections.
(pimples, diarrhea, sore
throat, tonsillitis)

23. Kingdom Protista
3 Groups of Protist:
1. Algae
2. Dinoflagellates
3. Euglena

24. 1. Algae
- Types:
a. Green Algae
uses: source of food
(ex: pukpuklo)

25. b. Brown Algae (Largest)
uses: - use to make ice
cream
- use to make candy
- use to make
cosmetic products

26. c. Red Algae
uses: - sources of agar
(gulaman)

27. 2. Dinoflagellates
- they cause Red Tide
* “DO NOT EAT SEA
CLAMS AND FISHES DURING
RED TIDE”

28. 3. Euglena
- Amoeba
(cause Amoebiasis)
* Amoeba is present in
ground water.
