What is osmosis? Explain giving an example.

The movement of water molecules from a region of its higher concentration to a region of its lower concentration, across a semipermeable membrane is called osmosis.

For example - If you put a carrot in salty water, the salt water will pull out the water from inside the carrot (which is mostly made up of water). Within a few hours, the carrot will be limp, its cells shriveled.
