Let's solve
Task 1 from the worksheet titled *"Bab 1.1: Dunia Mikroorganisma"* (Chapter 1.1: World of Microorganisms). The task asks you to
name the group (kumpulan) of microorganisms for each given example.
We are given five images of microorganisms and need to match each with its correct group from the list below:
- Virus
- Bakteria (Bacteria)
- Protozoa (Protozoa)
- Kulat (Fungi)
- Alga (Algae)
---
Step-by-step identification:
####
1. First Image (Green, oval-shaped with a flagellum and nucleus-like structure):
- This organism has:
- A single nucleus
- One long flagellum
- Membrane-bound organelles
- It looks like
Paramecium or
Euglena, which are unicellular eukaryotes.
- This is a
Protozoa (Protozoan).
✔ Group: Protozoa
---
####
2. Second Image (Hexagonal head with tail fibers – typical "bacteriophage" shape):
- This has:
- A capsid (head)
- Tail fibers
- No cellular structure
- Cannot reproduce independently
- This is a
virus (specifically a bacteriophage).
- Viruses are not cells; they are genetic material in a protein coat.
✔ Group: Virus
---
####
3. Third Image (Mycelium with spores on stalks – labeled sporangiospore, sporangium, stolon, rhizoids):
- This shows:
- A network of hyphae (filaments)
- Sporangia producing spores
- Rhizoids anchoring it
- This is characteristic of
fungi, specifically
Rhizopus (bread mold).
✔ Group: Kulat (Fungi)
---
####
4. Fourth Image (Blue, elongated cell with cilia and internal structures like nuclei):
- Features:
- Ciliated surface
- Multiple nuclei
- Complex internal structure
- This resembles
Paramecium, a well-known protozoan.
- It is a unicellular eukaryote that moves using cilia.
✔ Group: Protozoa
---
####
5. Fifth Image (Rod-shaped cell with flagellum and pili):
- Features:
- Prokaryotic cell (no nucleus)
- Has flagella and pili
- Rod-shaped (bacillus form)
- This is a classic representation of
bacteria, such as *Escherichia coli* or *Salmonella*.
✔ Group: Bakteria (Bacteria)
---
Final Answer Table:
| Example of Microorganisms | Groups of Microorganism |
|---------------------------|--------------------------|
| 🟩 Green protozoan with flagellum |
Protozoa |
| 🔵 Bacteriophage (virus) |
Virus |
| 🟨 Mold with spores and mycelium |
Kulat (Fungi) |
| 🟦 Ciliated protozoan (Paramecium-like) |
Protozoa |
| 🔴 Rod-shaped bacterium with flagellum |
Bakteria (Bacteria) |
---
Summary of Answers:
1.
Protozoa
2.
Virus
3.
Kulat (Fungi)
4.
Protozoa
5.
Bakteria (Bacteria)
>
✔ Note: Two of the organisms belong to
Protozoa, which is correct — there are many types of protozoans.
