Osmosis is the process in which solvent molecules pass through a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. In simpler terms, it is the movement of water molecules from a region of high water concentration to a region of low water concentration across a selectively permeable membrane.
Osmosis plays a significant role in plant cells as it allows the plant to maintain its shape and structure. The plant cell membrane is selectively permeable, allowing water molecules to pass through via osmosis. When a plant cell is in a hypotonic solution (low solute concentration), water will move into the cell, causing it to swell and potentially burst. When a plant cell is in a hypertonic solution (high solute concentration), water will move out of the cell, causing it to shrink and potentially die. When the plant cell is in an isotonic solution (equal solute concentration), water movement will be balanced, and the cell will be stable. Therefore, osmosis affects plant cells by either maintaining their shape and structure or causing damage if the balance is disrupted.

Osmosis is the movement of water from an area of high water concentration to an area of low water concentration across a semipermeable membrane. In plant cells, the semipermeable membrane is the cell membrane. The cell membrane allows water molecules to pass through, but it does not allow dissolved substances to pass through.
When a plant cell is placed in a solution that has a higher concentration of dissolved substances than the cell, water will move out of the cell by osmosis. This is because the water molecules will move from an area of high water concentration (inside the cell) to an area of low water concentration (outside the cell). As water moves out of the cell, the cell will shrink. This is called plasmolysis.
Osmosis is the process by which water moves from an area of high concentration to an area of low concentration through a semi-permeable membrane. This process is important for plant cells, as it helps them to regulate their water balance and absorb nutrients from the soil. Osmosis also helps to maintain a balance of water and solutes in the plant cells, which is essential for the plant's health and growth.
Osmosis is a process by which plants maintain their water content despite the constant water loss due to transpiration. This process controls the cell to cell diffusion of water. Osmosis induces cell turgor which regulates the movement of plants and plant parts. Osmosis also controls the dehiscence of fruits and sporangia.
Plants cells placed in a solution with a high water concentration compared to their contents e.g. pure water will gain water by osmosis and swell up until their cytoplasm and cell membrane are pushing against their cell wall.
