Living cells vs. Dead cells
Living cells have the ability to absorb water through osmosis, while dead cells do not have this capability. This is due to several key factors that differentiate the two types of cells.

Cell Membrane Integrity
- Living cells have an intact cell membrane that is selectively permeable, allowing water molecules to pass through via osmosis.
- Dead cells, on the other hand, have a compromised cell membrane that is no longer selectively permeable, making it impossible for water to be absorbed through osmosis.

Cell Functions
- Living cells are actively engaged in various cellular processes that require water for metabolic reactions and maintaining cellular functions.
- Dead cells no longer carry out these functions, rendering the need for water absorption through osmosis unnecessary.

Energy Production
- Living cells require water for energy production through processes like cellular respiration.
- Dead cells do not produce energy and therefore do not require water for this purpose.

Conclusion
In conclusion, living cells can absorb water through osmosis due to their intact cell membrane, active cellular functions, and energy production requirements. On the other hand, dead cells lack these essential characteristics, preventing them from absorbing water through osmosis.
