Movement of a molecule across a membrane independent of other molecules is known as –

Options

A. Apoplast
B. Uniport
C. Antiport
D. Symport

Answer

### Step-by-Step Solution:

1. **Understanding the Question**: The question asks for the term that describes the movement of a molecule across a membrane independently of other molecules.

2. **Identifying Key Terms**: The key terms in the question are "movement of a molecule," "across a membrane," and "independent of other molecules."

3. **Analyzing the Options**:
- **Epoplast**: This term is not commonly used in the context of membrane transport.
- **Unipot**: This refers to the movement of a single molecule across a membrane without the influence of other molecules.
- **Antipot**: This involves the movement of two different molecules in opposite directions across a membrane.
- **Sympot**: This refers to the movement of two different molecules in the same direction across a membrane.

4. **Selecting the Correct Answer**: Since the question specifies the movement of a single molecule independent of others, the correct answer is **Unipot**.

5. **Conclusion**: The movement of a molecule across a membrane independent of other molecules is known as **Unipot**.
