Highlight three major roles of water in a cell?

1. Water is a universal solvent in cells, allowing for the dissolution and transport of various molecules and ions necessary for cellular processes. It also helps in the breakdown of larger molecules through hydrolysis reactions.

2. Water plays a crucial role in maintaining the structural integrity of cells by filling the vacuoles and providing turgor pressure, which helps cells maintain their shape and rigidity.

3. Water is involved in various metabolic reactions within cells, serving as a reactant or product in many biochemical processes such as photosynthesis, respiration, and protein synthesis. It also helps regulate temperature within cells by absorbing and releasing heat during metabolic reactions.

1. Solvent: Water is the primary solvent in cells, dissolving and carrying a multitude of molecules, ions, and nutrients, enabling biochemical reactions and transport processes.

2. Temperature regulation: Water's high specific heat capacity and heat of vaporization allow cells to maintain a stable temperature even under fluctuating environmental conditions. It absorbs and releases heat to prevent extreme temperature changes.

3. Structural support: Water provides structural support to cells, giving them their shape and turgor. It fills intracellular spaces, maintaining cell volume and rigidity, and cushions organelles and other cellular components.
