Question

With the help of a diagram, explain osmosis in plant cells.

Answer 1

Water moves into plant cells by osmosis as follows:

1. The cell membrane of the plant cell is a partially permeable membrane.
2. The cell sap inside the vacuole is a strong solution.
3. Water passes into the plant cell by osmosis.
4. The concentration of the sap in the vacuole is now weaker.
5. Water passes from the weak solution into the strong solution in the next cell by osmosis.
