Water Movement in and out of a Cell's Vacuole

Which way will the water go into the vacuole or out of the vacuole?

A) Into the vacuole

B) Out of the vacuole

C) Both ways

D) No movement

Final answer: Water movement in or out of a cell's vacuole depends on the relative solute concentrations of the intracellular and extracellular environments.

Answer:

Water movement into or out of a vacuole in a cell varies depending on the osmotic conditions of the surrounding environment relative to the inside of the cell.

Water movement in and out of a cell's vacuole plays a crucial role in maintaining cellular homeostasis and ensuring the cell functions properly. This movement is driven by the process of osmosis, which involves the movement of water molecules across a selectively permeable membrane.

In a hypotonic solution, where the solute concentration is lower outside the cell compared to inside the cell, water will flow into the vacuole. This influx of water can lead to the cell swelling and potentially bursting if the cell wall is not strong enough to withstand the pressure.

Conversely, in a hypertonic solution, where the solute concentration is higher outside the cell, water will move out of the vacuole. This can cause the cell to shrink and undergo plasmolysis, where the cell membrane detaches from the cell wall.

When the solution is isotonic, meaning the solute concentrations inside and outside the cell are equal, there is no net movement of water into or out of the vacuole. This allows the cell to maintain its shape and function properly.

Overall, the movement of water in and out of a cell's vacuole is crucial for maintaining the cell's internal environment and ensuring its survival in changing external conditions.
