Importance of Water.

Importance of Water
Our Earth seems to be unique among the other known celestial bodies. It has water, which covers three-fourths of its surface and constitutes 60-70 wt % of the living world. Water regenerates and is redistributed through evaporation, making it seem endlessly renewable. So why worry?

Actually, only 1% of the world's water is usable to us. About 97% is salty sea water, and 2% is frozen in glaciers and polar ice caps. Thus that 1% of the world's water supply is a precious commodity necessary for our survival. Dehydration (lack of water) will kill us faster than starvation (lack of food). Since the plants and animals we eat also depend on water, lack of it could cause both dehydration and starvation. The scenario gets worse. Water that looks drinkable can contain harmful elements, which could cause illness and death if ingested.

Good water is essential to body cleansing. It's obvious. It sounds like a truism. Your body goes down fast without water. Making up almost three-fourths of the body, every cell is regulated, monitored and dependent on an efficient flow of water. Not one of the processes in our bodies could take place without water. Water is something that we take for granted. But how many of us really understand how essential water is or what happens to our body if it doesn't receive pure water every day, free of chemicals and pollutants?

· Water is the adhesive that bonds your cell architecture. When you get enough water fluid retention decreases, and gland and hormone functions improve.
· Water regulates your body temperature, maintains your equilibrium and helps the liver break down and release more fat.
· Water carries every nutrient, mineral, vitamin, protein, hormone and chemical messenger in your body to its destination.
· Proteins and enzymes, the basis for your body's healing capacity, function efficiently only when you have enough water.
· Your daily energy depends on water, because your body's chemical reactions are water-dependent. Just like a hydro-electric system, the energy generated by your body's water is used by your two vital cell battery systems, ATP and GTP.
· Your brain tissue is 85% water. Messages from your brain to everywhere else in your body are transported on "waterways."

Water is essential to the cleansing processes of your body.
-It lubricates and flushes wastes and toxins from all cells.
-It cleanses the internal organs.
-It helps eliminate toxins from the bloodstream.

Drinking enough water is critical to keep your skin soft and supply, your brain sharp and your elimination systems regular. But there's another side to the water story. Most Americans have reduced their intake of fats (including the good Omega-3 fats) to the point that their bodies don't hold and use the water they do take in. It's one of the reasons I recommend adding more sea greens to your diet ...

How much is enough? Your body needs about three quarts of replacement water every day under normal conditions. Strenuous activity, summer temperatures, or a diet that's high in salt increase this requirement. Your foods provide up to 11/2 quarts of water per day. (Fruits and vegetables are more than 90% water. Even dry foods like bread are about 35% water.) Water for metabolism is produced as part of the food digestion process, yielding as much as a pint per day.

Plants

Water Regulation in Plants

A plant requires water as an essential ingredient of photolysis, the photochemical stage of photosynthesis where water is split using light energy. This is the part of the process in which a plant obtains its' energy, and thus illustrates the importance of water to a plant.

Water is absorbed from the root and is transported to all areas of the plant, this passage of water is called the . Water is absorbed by the of a plant, which possess many with large surface areas for extensive absorbing of water. We have already discussed how occurs across a in preceding tutorials, and this is the case here.

When water is required an the concentration of water in the roots is low, water is absorbed from the higher concentration of water found in the ground. This same occurrence goes for the concentration difference between cells, as the water rich root cells allow osmosis to occur up the plant until their is an equal concentration throughout the organism.

Scientists were previously perplexed by the nature in which water could defy the force of gravity and move up the plant, since water molecules are heavier than the surrounding atmosphere. Through extensive studies, the following factors are thought to play a role in pushing water up the transpiration stream.
