Why do cell walls such as in an herb become brittle when dried? What is water doing exactly to hold it together before it was dried?
Cell walls in plants, such as herbs, become brittle when dried due to the loss of turgor pressure, which is maintained by water within the cells. Turgor pressure is essential for cell rigidity; without sufficient water, cells lose this pressure and subsequently wilt. This process highlights the critical role of water in maintaining cell structure and integrity in plant tissues.
