Options

A. They divide by fission
B. They posses linear DNA molecule
C. They produce energy
D. They have 70s ribosomes

Answer

To solve the question "Pick the wrong statement about mitochondria," we will analyze each of the provided options step by step:

### Step 1: Analyze the First Option
- **Statement**: "They divide by fission."
- **Explanation**: Mitochondria do indeed divide by a process called fission. This is a correct statement.

### Step 2: Analyze the Second Option
- **Statement**: "It possesses linear DNA molecule."
- **Explanation**: Mitochondria actually contain circular DNA, similar to bacterial DNA. Therefore, this statement is incorrect.

### Step 3: Analyze the Third Option
- **Statement**: "They produce energy."
- **Explanation**: Mitochondria are known as the powerhouse of the cell because they are responsible for producing energy (ATP) through cellular respiration. This is a correct statement.

### Step 4: Analyze the Fourth Option
- **Statement**: "They have 70S ribosomes."
- **Explanation**: Mitochondria do contain 70S ribosomes, which is a characteristic of prokaryotic cells. This is a correct statement.
