The inner wall of each guard cell towards the pore or stomatal aperture is thick and elastic.

Answer

### Step-by-Step Solution:

1. **Understanding Guard Cells**: Guard cells are specialized cells that surround the stomatal pores on the surface of leaves. They play a crucial role in regulating the opening and closing of these pores, which is essential for gas exchange and transpiration in plants.

2. **Structure of Guard Cells**: Each guard cell has two walls: an outer wall and an inner wall. The outer wall is generally thinner and more elastic, allowing for flexibility during the opening and closing of the stomata.

3. **Characteristics of the Inner Wall**: The inner wall of the guard cells, which faces the stomatal pore, is thicker and less elastic (inelastic). This structure helps maintain the shape and stability of the stomatal aperture during the process of opening and closing.

4. **Evaluating the Statement**: The statement in the question claims that "the inner wall of each guard cell towards the pore or stomatal aperture is thick and elastic." Since we established that the inner wall is thick but inelastic, the statement is incorrect.

5. **Conclusion**: Therefore, the answer to the question is that the statement is **false**.
