The correct Answer is:
To solve the question regarding the type of cell junction that prevents substances from leaking across a tissue, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Types of Cell Junctions**: - There are several types of cell junctions in tissues, including tight junctions, adhering junctions, and gap junctions. 2. **Identify the Function of Each Junction**: - **Tight Junctions**: These junctions create a barrier that prevents the passage of substances between cells. They are crucial in maintaining the integrity of epithelial tissues by sealing cells together. - **Adhering Junctions**: These junctions provide mechanical stability and allow for some transfer of substances, but they do not completely prevent leakage. - **Gap Junctions**: These junctions allow for the direct transfer of ions and small molecules between adjacent cells, facilitating communication. 3. **Determine Which Junction Prevents Leakage**: - Since tight junctions are specifically designed to prevent substances from leaking across the tissue, they are the correct answer to the question. 4. **Conclude the Answer**: - The type of cell junction that helps to stop substances from leaking across a tissue is **Tight Junctions**. ### Final Answer: The type of cell junction that helps to stop substances from leaking across a tissue is **Tight Junctions**. ---
