Explain the plant cell as an osmotic system.
The plasma membrane of plant cells alone or along with the vacuolar membrane and the cytoplasmic film is semi-permeable in nature. This membrane allows the free passage of water molecules but prevents the entry of certain molecules. In-plant cells, the cytoplasm is surrounded by a cell wall that is highly concentrated than the solution, which enters plant cells through osmosis. Therefore, plant cells function like the osmotic system if they meet the following two conditions: i. If there is a semipermeable membrane. ii. Since it has a much higher concentration of a liquid substance, hence, plant cells act as an osmotic system.
