The ribosomes present in the cytoplasm of the causative organism of cholera and Mitochondria of causative organism of malaria , respectively , are

Options

A. 70S and 70S
B. 70S and 80S
C. 80S and 70S
D. 80S and 80S

Answer

To solve the question regarding the ribosomes present in the cytoplasm of the causative organism of cholera and the mitochondria of the causative organism of malaria, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Causative Organisms**:
- The causative organism of cholera is *Vibrio cholerae*, which is a bacterium.
- The causative organism of malaria is *Plasmodium*, which is a protozoan.

2. **Determine the Type of Ribosomes in *Vibrio cholerae***:
- Bacteria, including *Vibrio cholerae*, contain 70S ribosomes in their cytoplasm. This is characteristic of prokaryotic cells.

3. **Determine the Type of Ribosomes in *Plasmodium***:
- *Plasmodium*, being a eukaryotic organism, has 80S ribosomes in its cytoplasm. However, the mitochondria of *Plasmodium* contain 70S ribosomes, similar to those found in prokaryotes.

4. **Summarize the Findings**:
- The ribosomes in the cytoplasm of *Vibrio cholerae* are 70S.
- The ribosomes in the mitochondria of *Plasmodium* are also 70S.

5. **Choose the Correct Option**:
- Based on the analysis, the correct answer is that both the ribosomes in the cytoplasm of the cholera-causing organism and the mitochondria of the malaria-causing organism are 70S.

### Final Answer:
The ribosomes present in the cytoplasm of the causative organism of cholera and the mitochondria of the causative organism of malaria, respectively, are **70S and 70S**.
