Match the following cell structure with its characteristic feature:

1. Tight junctions - Cement neighbouring cells together to form sheet.
2. Adhering junctions - Transmit information through chemical to another cells.
3. Gap junctions - Establish a barrier to prevent leakage of fluid across epithelial cells.
4. Synaptic junctions - Cytoplasmic channels to facilitate communication between adjacent cells.

Correct answer: Tight junctions - Cement neighbouring cells together to form sheet.

Solution

Tight junctions form a continuous seal between neighboring epithelial cells, helping them act as a sheet and preventing leakage between cells. The other options describe different junction types: gap junctions allow direct communication, adhering junctions provide mechanical attachment, and synaptic junctions transmit signals.
