Name two cell organelles that are double membrane bound. What are the characteristics of these two organelles? State their functions and draw labelled diagrams of both.

Explanation

### Step-by-Step Solution

1. **Identify Two Double Membrane-Bound Organelles**:
- The two cell organelles that are double membrane-bound are **Mitochondria** and **Chloroplasts**.

2. **Characteristics of Mitochondria**:
- **Structure**: Mitochondria have an outer membrane and a highly folded inner membrane, which creates compartments. The space inside the inner membrane is called the **matrix**.
