Question

Match the following:

1. Tight junctions	i. Help cells communicate with each other
2. Gap junctions	ii. Provides anchoring function
3. Adherens junctions	iii. Prevent substances from leaking across the tissue

• A. 1-iii, 2-ii, 3-i
• B. 1-ii, 2-iii, 3-i
• C. 1-iii, 2-i, 3-ii
• D. 1-i, 2-iii, 3-ii

Answer 1

The correct option is C 1-iii, 2-i, 3-ii

There are 3 types of cell junctions:
i. Tight junctions: These junctions are formed by adjacent epithelial cells which are tightly packed together. These junctions help prevent substances from leaking across the tissue.

ii. Gap junctions: These junctions are formed by connecting the cytoplasm of adjoining cells. This facilitate cells to communicate with each other.

iii. Adherens junctions: These junctions cement the adjacent cells together. They serve anchoring function.
