| (b) | Adhering junctions | (ii) | Transmit information through chemicals to another cell |
| (c) | Gap junctions | (iii) | Establish a barrier to prevent leakage of fluid across epithelial cells |
| (d) | Synaptic junctions | (iv) | Cytoplasmic channels to facilitate communication between adjacent cells |
Select the correct option from the following:

| 3. | Separate two cells from each other |
| 4. | Stop substances from leaking across a tissue |
