Detailed explanation-1: -Water is essential for life. Its special properties make water the single most important molecule in plant life. Which of the following properties of water enables it to move from the roots to the leaves of plants? Water exhibits cohesive behavior.
Detailed explanation-2: -Water’s extensive capability to dissolve a variety of molecules has earned it the designation of “universal solvent, ‘’ and it is this ability that makes water such an invaluable life-sustaining force. On a biological level, water’s role as a solvent helps cells transport and use substances like oxygen or nutrients.
Detailed explanation-3: -Discussion of the properties of water that make it essential to life as we know it: polarity, “universal” solvent, high heat capacity, high heat of vaporization, cohesion, adhesion and lower density when frozen.
Detailed explanation-4: -Capillary action helps bring water up into the roots. With the help of adhesion and cohesion, water can work it’s way all the way up to the branches and leaves.
Detailed explanation-5: -Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it!
