Question

sharqan placed a potato slice in salt water. after some time he noticed that the slice of potato became limp. why did this happen to the potato slice? a the potato was getting old. b the potato cells lost water to the surroundings. c the potato cells gained water from the surroundings. d the potato cells had no exchange of materials with the environment.

Explanation:

When a potato slice is placed in salt - water, which is a hypertonic solution compared to the potato cells' internal environment, water moves out of the potato cells by osmosis. Osmosis is the movement of water from an area of lower solute concentration (inside the potato cells) to an area of higher solute concentration (the salt - water). This causes the potato cells to lose water and become flaccid, resulting in the potato slice becoming limp.

Answer:

B. The potato cells lost water to the surroundings
