Which of the following best describes the function of tight junctions?
Understand the Problem
The question is asking about the function of tight junctions in cells. Tight junctions are cellular structures that serve specific purposes, and the question requires identifying the option that accurately describes their primary function.
Answer
Tight junctions prevent the passage of substances between adjacent animal cells, acting as a watertight seal.
Tight junctions prevent the passage of substances between adjacent animal cells. They act as a watertight seal, typically found in epithelial tissues that line internal organs and cavities.
Answer for screen readers
Tight junctions prevent the passage of substances between adjacent animal cells. They act as a watertight seal, typically found in epithelial tissues that line internal organs and cavities.
More Information
Tight junctions are crucial for maintaining the integrity of epithelial barriers and regulating the movement of molecules between cells. They also help to maintain cell polarity by preventing the mixing of apical and basolateral membrane components.
