1.Osmosis: The dilute glucose solution has a higher concentration of water compared to the cell cytoplasm. Therefore, water molecules move into the cell by osmosis.
2. Increased Cell Size: As water enters the cell, the cell swells and increases in size.
3. Turgor Pressure: The increased cell volume causes the cell membrane to press against the rigid cell wall, creating turgor pressure. Turgor pressure is essential for maintaining the shape and rigidity of the plant cell.
4. Plasmolysis Reversal: If the palisade cell was previously plasmolyzed (shrunken due to water loss) when placed in a concentrated solution, the addition of dilute glucose solution reverses the plasmolysis. The cell regains its normal shape and size as water moves back into the cell.
In summary, when a palisade cell is put in a dilute glucose solution, water enters the cell, causing it to swell, increase in size, and develop turgor pressure. If the cell was previously plasmolyzed, the plasmolysis is reversed, and the cell returns to its normal state.
