Which of the following is capable of reproducing sexually ?

Options

A. Amoeba
B. Plasmodium
C. Euglena
D. Trypanosoma

Answer

To determine which of the following organisms is capable of reproducing sexually, let's analyze each option provided: amoeba, plasmodium, euglena, and trypanosoma.

### Step-by-Step Solution:

1. **Understand the Types of Reproduction**:
- There are two main types of reproduction: sexual and asexual.
- Sexual reproduction involves the combination of genetic material from two parents (male and female).
- Asexual reproduction does not involve the fusion of gametes and can occur through methods like binary fission, budding, or multiple fission.

2. **Analyze Amoeba**:
- Amoeba primarily reproduces asexually through a process called multiple fission.
- In multiple fission, a single amoeba divides to form multiple daughter amoebae.
- **Conclusion**: Amoeba does not reproduce sexually.

3. **Analyze Euglena**:
- Euglena reproduces asexually through binary fission, where one organism splits into two identical organisms.
- **Conclusion**: Euglena does not reproduce sexually.

4. **Analyze Trypanosoma**:
- Trypanosoma also reproduces asexually, typically through binary fission or multiple fission.
- **Conclusion**: Trypanosoma does not reproduce sexually.

5. **Analyze Plasmodium**:
- Plasmodium is unique among the options as it can reproduce both sexually and asexually.
- In its life cycle, Plasmodium undergoes sexual reproduction in its vector (mosquito) and asexual reproduction in the human host.
- **Conclusion**: Plasmodium is capable of reproducing sexually.

6. **Final Answer**:
- The organism that is capable of reproducing sexually among the given options is **Plasmodium**.
