Match the column I with Column II:-
`{:("Column I","Column II"),((A)" Unicellular",(i)" Spirogyra"),((B)" Colonial",(ii)" Kelps"),((C)" Filamentous",(iii)" Volvox"),((D)" massive plant bodies",(iv)" Chlamydomonas"):}`

Answer

To solve the matching question, we need to pair the items from Column I with the appropriate items from Column II based on their characteristics. Let's analyze each item step by step.

### Step 1: Identify the characteristics of each item in Column I

1. **Unicellular**: This refers to organisms that consist of a single cell.
2. **Colonial**: This refers to organisms that live in groups or colonies, consisting of multiple cells that may be connected.
3. **Filamentous**: This refers to organisms that have a thread-like structure, often forming long chains or filaments.
4. **Massive plant bodies**: This refers to large organisms that form substantial structures, typically seen in larger algae or plants.

### Step 2: Analyze Column II options

1. **Spirogyra**: This is a type of filamentous green algae.
2. **Kelps**: These are large brown algae that form massive plant bodies in marine environments.
3. **Volvox**: This is a colonial green algae that forms spherical colonies.
4. **Chlamydomonas**: This is a unicellular green algae.

### Step 3: Match the items

- **A (Unicellular)**: The correct match is **(iv) Chlamydomonas** because it is a unicellular organism.
- **B (Colonial)**: The correct match is **(iii) Volvox** because it forms colonies.
- **C (Filamentous)**: The correct match is **(i) Spirogyra** because it is filamentous in structure.
- **D (Massive plant bodies)**: The correct match is **(ii) Kelps** because they are large brown algae that form massive structures.

### Final Matches

- A → (iv) Chlamydomonas
- B → (iii) Volvox
- C → (i) Spirogyra
- D → (ii) Kelps

### Summary of Matches

- A (Unicellular) → (iv) Chlamydomonas
- B (Colonial) → (iii) Volvox
- C (Filamentous) → (i) Spirogyra
- D (Massive plant bodies) → (ii) Kelps
