1. Complete the text using the words below:

Words to use:
- DIVIDING
- BY PRODUCING SPORES
- MULTICELLULAR
- UNICELLULAR
- SPORES

> *(Note: Words can be used more than once.)*

---

#### a) Monera are ________________ organisms. They reproduce by ________________.

- Monera (like bacteria and cyanobacteria) are unicellular organisms.
- They reproduce by dividing (binary fission).

✔ Answer:
Monera are UNICELLULAR organisms. They reproduce by DIVIDING.

---

#### b) Most fungi are ________________, but some are ________________. They reproduce by producing ________________.

- Most fungi are multicellular (like mushrooms, molds).
- Some fungi are unicellular (like yeast).
- Fungi reproduce by producing spores.

✔ Answer:
Most fungi are MULTICELLULAR, but some are UNICELLULAR. They reproduce by producing SPORES.

---

#### c) Protists can be ________________ or ________________. They reproduce in two ways; some ________________ but others ________________.

- Protists can be unicellular or multicellular (though most are unicellular).
- Reproduction: Some divide, others produce spores.

✔ Answer:
Protists can be UNICELLULAR or MULTICELLULAR. They reproduce in two ways; some DIVIDING but others BY PRODUCING SPORES.

> *(Note: "by producing spores" is a phrase, so it should be used as is.)*

---

✔ Final Answers for Question 1:

a) Monera are UNICELLULAR organisms. They reproduce by DIVIDING.
b) Most fungi are MULTICELLULAR, but some are UNICELLULAR. They reproduce by producing SPORES.
c) Protists can be UNICELLULAR or MULTICELLULAR. They reproduce in two ways; some DIVIDING but others BY PRODUCING SPORES.

2. Write the name of the kingdom in each picture: Fungi, Monera, Protocista

Now let’s identify each image:

---

#### Image 1 (Top left): Royal Baking Powder box

This is not a living organism. But since it's labeled with a brand, it's likely a trick — maybe it's meant to represent yeast, which is used in baking?

Wait — yeast is a fungus (specifically, a unicellular fungus). So if this is implying yeast, then it belongs to Fungi.

✔ Answer: FUNGI

---

#### Image 2 (Top middle): A green cell with flagella

This looks like a protist, possibly an Euglena or similar organism. It has a nucleus, flagella, and chloroplasts (green), so it’s a photosynthetic protist.

✔ Answer: PROTISTA

---

#### Image 3 (Top right): Mushrooms

Clearly mushrooms → Fungi

✔ Answer: FUNGI

---

#### Image 4 (Bottom left): A petri dish with colorful colonies

This shows microbial growth, likely bacteria (colored colonies on agar). This is typical of Monera (prokaryotes).

✔ Answer: MONERA

---

#### Image 5 (Bottom middle): Green seaweed-like plant

This looks like algae, such as Ulva or sea lettuce. Algae are often classified under Protista (especially if they’re not complex plants).

✔ Answer: PROTISTA

---

#### Image 6 (Bottom right): A rod-shaped bacterium with antibiotics nearby

This is clearly a bacterium (rod-shaped, no nucleus), and the antibiotics suggest it's a pathogenic bacterium.

✔ Answer: MONERA

---

✔ Final Answers for Question 2:

| Image | Kingdom |
|-------|-------------|
| 1 (Baking powder) | FUNGI (representing yeast) |
| 2 (Flagellated cell) | PROTISTA |
| 3 (Mushrooms) | FUNGI |
| 4 (Petri dish colonies) | MONERA |
| 5 (Green algae) | PROTISTA |
| 6 (Bacterium) | MONERA |

✔ Full Completed Worksheet:

#### 1. Fill in the blanks:

a) Monera are UNICELLULAR organisms. They reproduce by DIVIDING.
b) Most fungi are MULTICELLULAR, but some are UNICELLULAR. They reproduce by producing SPORES.
c) Protists can be UNICELLULAR or MULTICELLULAR. They reproduce in two ways; some DIVIDING but others BY PRODUCING SPORES.

#### 2. Name the kingdom:

1. FUNGI
2. PROTISTA
3. FUNGI
4. MONERA
5. PROTISTA
6. MONERA

📌 Summary:

- Monera: Unicellular, prokaryotic, divide by binary fission.
- Fungi: Mostly multicellular, reproduce via spores; includes yeasts (unicellular).
- Protista: Can be unicellular or multicellular; diverse reproduction methods (division or spores).
