In the carrot experiment to demonstrate osmosis, we would expect the string around the carrot placed in salt water to be tighter than the one placed in tap water, because both the salt and the water diffuse into the carrot.
Osmosis
The spontaneous movement of solvent molecules through a semi-permeable membrane from a region of lower solute concentration to a region of higher solute concentration.
Salt Water
Water that contains a high concentration of dissolved salts, commonly found in the oceans.
- Comprehend the effect of osmotic pressure on the shape and structure of cells.
- Identify the differences between isotonic, hypertonic, and hypotonic solutions, and explore their influences on cell behavior.

Final Answer :
False
Explanation :
In the carrot experiment, the string around the carrot placed in salt water becomes looser, not tighter, because water diffuses out of the carrot into the salt water (a hypertonic solution) to balance the concentration of solutes, causing the carrot to shrink.
