Question
Plans that live near the sea can often get flooded with seawater This causes them to
wilt. Using the principals of osmosis explain why this happens.
Answer
Osmosis is the process by which water molecules move from an area of higher concentration to an area of lower concentration. When plants are flooded with seawater, the concentration of salt in the seawater is higher than the concentration of salt in the plant cells. This causes water molecules to move from the plant cells into the seawater, resulting in the wilting of the plant.
