Verified step by step guidance

Understand the concept of turgor pressure: Turgor pressure is the pressure exerted by the cell contents against the cell wall in plant cells. It is crucial for maintaining the structure and rigidity of the plant.

Identify the types of solutions: Hypotonic, isotonic, and hypertonic solutions differ in their solute concentration relative to the inside of the cell.

Define a hypotonic solution: A hypotonic solution has a lower concentration of solutes compared to the inside of the cell, leading to water moving into the cell.

Explain the effect of a hypotonic solution on plant cells: When plant cells are placed in a hypotonic solution, water enters the cells, causing them to swell and become turgid due to increased turgor pressure.

Contrast with isotonic and hypertonic solutions: In isotonic solutions, there is no net movement of water, and in hypertonic solutions, water moves out of the cell, causing it to shrink. These do not lead to turgor in plant cells.
