Refer to the given key and answer the following questions.
(i) Membrane with pores - P
(ii) Inner membrane with stalked particles - Q
(iii) At places, the inner membrane is connected to stacks-like structures -R
(iv) Sac like organelle containing hydrolytic enzymes - S
(v) Membraneless organelle composed of one large and one small subunit - T
Select the correct match of organelle and its function.

Options

A. P - Protein synthesis
B. R - Fat synthesis
C. S - Disposal of worn out cell organelle
D. T - Energy production

Answer

To solve the question, we need to match each organelle with its correct function based on the provided key. Let's go through each organelle step by step.

### Step-by-Step Solution:

1. **Identify Organelle P**:
- Description: Membrane with pores.
- Likely Identification: This is the nuclear pore, which is found in the nuclear membrane and allows the transport of materials in and out of the nucleus.
- Function: Involved in the transport of molecules, not directly in protein synthesis.

2. **Identify Organelle Q**:
- Description: Inner membrane with stalked particles.
- Likely Identification: This refers to the inner membrane of mitochondria, which has stalked particles known as ATP synthase.
- Function: Involved in ATP (energy) production.

3. **Identify Organelle R**:
- Description: Inner membrane connected to stack-like structures.
- Likely Identification: This is also associated with mitochondria, specifically the cristae, which are the folds of the inner membrane.
- Function: Involved in energy production.

4. **Identify Organelle S**:
- Description: Sac-like organelle containing hydrolytic enzymes.
- Likely Identification: This is a lysosome.
- Function: Responsible for the breakdown and disposal of worn-out cell organelles and macromolecules.

5. **Identify Organelle T**:
- Description: Membraneless organelle composed of one large and one small subunit.
- Likely Identification: This is a ribosome.
- Function: Involved in protein synthesis.

### Correct Match of Organelle and Function:
- **P (Nuclear Pore)**: Involved in transport, not protein synthesis.
- **Q (Mitochondria)**: Involved in energy production.
- **R (Cristae of Mitochondria)**: Involved in energy production.
- **S (Lysosome)**: Involved in disposal of worn-out cell organelles (correct).
- **T (Ribosome)**: Involved in protein synthesis.

### Conclusion:
The correct match from the options provided is:
- **S (Lysosome)** is involved in the disposal of worn-out cell organelles.

### Final Answer:
The correct answer is option 3: S (Lysosome) is involved in the disposal of worn-out cell organelles.
