microorganism 2nd quarter grade 5

1. Microorganisms

2. Living things may be multicellular or
unicellular. Unicellular are mostly
invisible to the naked eye. A microscope
is needed for them to be visible, they are
referred to as microscopic organisms or
“microorganisms” Microorganisms

3. micros means “small” and
organismos means “organism” Microorganisms

4. microorganisms are very diverse.
they can be found everywhere on
Earth. They can live on land, water
and in air. Microorganisms

5. usually associated with diseases.
A disease-causing
microorganisms is called a
PATHOGEN.

6. As they invade the body of the
host, they also produce harmful
waste materials and various type
of toxins that harm and destroy
our cells. BACTERIA

7. Are round or spherical
bacterial cells.
COCCI

8. rod-shaped bacteria.
An example of these is
lactobacillus, which is
good bacteria that is
used as a probiotic.
BACILLI

9. ECONOMIC
IMPORTANCE OF
BACTERIA

10. Human consider bacteria to be
dangerous organisms. This is
because of the harmful roles that
bacteria play in causing diseases
and food spoilage.

11. Harmful Effects
of Bacteria

12. type of bacteria that normally
lives in our intestines.
Although it helps the body
break down and digest food,
some e.coli can cause
infections.
E.COLI

13. are organisms that may exist
as either single-celled or
multicellular forms. Fungi like
molds and mushrooms.
FUNGI

14. Eukaryotic cells contain a nucleus and various organelles. They form
the building blocks of plants, animals, fungi, and protists, showing
diversity in function and structure across different life forms. Eukaryotic Cells –
Complex and Organized

15. Protists are often single-celled but can mimic characteristics of both plants
and animals. Paramecia and amoebas, with their movement and feeding
structures, showcase how dynamic these tiny life forms can be.
Protists – Versatile
Microorganisms

16. Flagella, cilia, and pseudopods allow cells to move through liquid
environments. These adaptations help microorganisms navigate,
feed, and respond to their surroundings. Cellular Movement
and Adaptation

17. Specialized cells like erythrocytes carry oxygen, while white blood cells
defend the body from pathogens. These tiny components are
constantly at work inside our bloodstream. Red Blood Cells and
Immune Cells

18. Bacteria vary widely in shape, function, and environment. Some are rod-
shaped, others spherical or spiral. Their structures help identify them and
understand their roles in nature and medicine.

Diversity

19. Viruses, like the spiky particles seen here, are not cells but
infectious agents. They invade host cells to replicate, making
them both fascinating and dangerous in medical science. Viruses and
Infection

20. Cell Structures and
Organelles Organelles such as mitochondria, Golgi bodies, and lysosomes perform
essential functions inside eukaryotic cells. Each plays a specific role in
energy production, protein processing, or waste removal.

21. Studying microscopic organisms deepens our understanding of life. From
laboratory science to medical applications, observing the smallest units of
biology reveals the complexity and beauty of life at its tiniest scale.
