Dried and wrinkled salad/lettuce can be "refreshed" by immersing it in cold water. This is due to osmosis. The process is shown in a time lapse video where things are speeded up 720x.

Passive Transport Special Types of Diffusion - Animated membrane physiology

There are three main types of passive transport:
-----------------------------------------------------------------------------
Simple diffusion – movement of small or lipophilic molecules (e.g. O2, CO2, etc.)
Osmosis – movement of water molecules (dependent on solute concentrations)
Facilitated diffusion – movement of large or charged molecules via membrane proteins (e.g. ions, sucrose, etc.)
