WebComplete answer: Flaccid cell means the cell in which the water flows in and out of the cell and is in equilibrium. In a flaccid Cell, the plasma membrane is not pressed tightly against the cell wall and it can be observed by putting the plant cell in the isotonic solution. WebThe cell becomes flaccid. It is becoming plasmolysed. Highly concentrated solution In a very concentrated solution, the cell undergoes full plasmolysis as the cells lose more water.

In reverse then the membrane shrinks from the sides, making the cell go flaccid cos it ... WebFlaccid – There will no net water movement so no pressure on the cell. It will be flaccid. Turgid – The water moves into the cell due to osmosis due to higher concentration of water outside the cell. The water will create pressure called turgor pressure on the cell wall making cell rigid and turgid. Osmosis in Animals
