Question

The following type of cell junction is not found in animal tissues

• A. Adhering junction
• B. Tight junction
• C. Gap junction
• D. Loose junction

Answer 1

The Correct Option is D

Let's evaluate the types of cell junctions:

• Adhering junction: These are present in animal tissues and help in adhering cells together, providing structural integrity.
• Tight junction: These are also present in animal tissues and seal the gaps between cells to prevent leakage of fluids between them.
• Gap junction: These are present in animal tissues and allow direct communication between cells by forming channels that permit the passage of small molecules and ions.
• Loose junction: This is not a recognized type of cell junction in animal tissues. The term "loose junction" is not used in the context of cellular junctions in animal tissues.

Therefore, the correct answer is (D) : Loose junction.
