Why life depends on water

• The properties of water are essential to all forms of life, including its ability to dissolve many substances, act as a solvent, store energy, transport nutrients, regulate temperature, and facilitate chemical reactions.
• Water has unique physical properties that make it an excellent solvent for biological processes.
• Water is the universal solvent because it can dissolve more substances than any other liquid.
• Water's high surface tension allows insects like water striders to walk on top of it without sinking.
• Water's polarity allows it to dissolve polar molecules like sugars and amino acids.
• Water's high specific heat capacity helps maintain constant temperatures within cells.
• Capillary action occurs due to adhesive forces between water molecules and solid surfaces.
• Water's viscosity helps prevent blood from flowing too quickly out of wounds.
• Water's density changes with temperature, affecting buoyancy and ice formation.
• Water has unique physical properties that make it an ideal medium for life, including high heat capacity, thermal conductivity, surface tension, viscosity, and density.
• Water's cohesion and adhesion allow it to form hydrogen bonds with itself and other molecules, creating structures such as ice crystals and cell membranes.
• water is a temperature buffer
• Metabolic reactions in cells are catalysed by enzymes
• Water helps to buffer temperature changes in cewlls because of its relatively high specific heat capacity
• Cohesion

  • water molecules stick together
  • Water as a habitat
  • Plants that have tubes which are vascular
• Adhesion is how water sticks to surfaces and is important for transport of substances
• benefits of cohesion, it conducts water through vascular plants with phloem and xylem and makes a habitats for organism
• Capillarity: The tendency of liquids to flow through capillaries, ascension of liquids through slime tubes, cylinders or permeable substance due to adhesive and cohesion
