Name the process that causes living cells to expand in size and shape when placed in a hypotonic solution.

Correct option is D

• Osmosis is the process that causes living cells to expand in size and shape when placed in a hypotonic solution.

• A hypotonic solution has a lower concentration of solutes compared to the inside of the cell. As a result, water moves into the cell through a selectively permeable membrane.

• This influx of water causes the cell to swell or expand. If too much water enters, it may lead to the cell bursting, especially in animal cells (a process called lysis).

• Osmosis plays a vital role in maintaining the cell's turgidity, which is crucial for plants to maintain their structure and support.

• Transpiration: This refers to the evaporation of water from plant leaves, contributing to water and nutrient transport.
• Diffusion: This is the movement of molecules from an area of higher concentration to an area of lower concentration. It can occur in both liquids and gases.
• Photosynthesis: This is the process by which plants convert light energy into chemical energy in the form of glucose, using carbon dioxide and water.
