The Biological Importance of Water
Water is vital to all living organisms, as a constituent of cells, a
reactant in metabolic reactions, and a solvent for aquatic organisms.
Without water life on earth would not exist. Water also provides an
environment for organisms to live in. Water consists of two hydrogen
atoms and one oxygen atom forming H2O. The two hydrogen’s and the
oxygen bond together through covalent bonding, which is the sharing of
electrons.
Water molecules are polar, with negative charge on the hydroxyl ions
and positive charge on hydrogen ions. The attraction of oppositely
charged poles of water molecules cause them to group together.
Attractive forces form hydrogen bonds. The substances that are able to
dissolve in water are known as hydrophilic substances.
Water can be used as temperature stabiliser. Lots of energy is
required to heat or boil water. The boiling point of water is 100 c
and the melting point is 0 c. At room temperature water is a liquid
because of hydrogen bonds, which hold the water molecules in a liquid
state. Water has a high specific heat, which is important inside cells
where metabolic reactions are enzyme controlled and externally to
provide a constant environment for aquatic organisms. High latent
heat, which is significant in temperature control where heat is used
for vaporization of water when sweating.
Water’s maximum density is at 4 c. As water-cools the density
increases. When water is in a liquid state the hydrogen bonds are weak
and can break easily because molecules move about. When water freezes,
the water molecules are no longer free to move and the hydrogen bonds
are permanently formed. Ice floats because ice is less dense than
water. This is because in the solid state the molecules are less
closely packed than in liquid water. Fish can survive in frozen lakes
because the ice on the surface insulates the water from further
freezing. Water is also good as a lubricant.
Water is the life blood of the earth. When water is healthy it has a complex structure that enables it to communicate information, carry energy, nutrients and healing, to self-cleanse and discharge wastes."
Water is more than something that we drink when we are thirsty or use to bath ourselves when we wish to be clean. Water makes up 71% of the Earth’s surface, being made of just two hydrogen atoms and one oxygen atom. It is vital for life to be sustained on Earth, allowing plants to survive and provide oxygen for animals to breathe and function while suppling animals with the core necessity that they need to strive towards survival. When we think of water, the first thing that comes to the minds of many is either in a glass or in a bottle, ready to be drank. When water is pure, it can usually be described as odorless and tasteless. Water samples may taste better than others. Due to water’s qualities of being an exceptional solvent, that being that water allows many compounds to be dissolved in it, this also water to carry the nutrients that ware vital to plant and animal health and even
Water has a great number of roles in living organisms, this is largely to do with the structure and covalent bonding in a single water molecule, and between water molecules. Around 75% of the earth is covered in water, and it is reffered to as the most important Biochemical. Its chemical symbol is: H2O In a water molecule there are two bonding pairs and two non-bonding pairs of electrons. These four pairs of electrons repel one another, forming a tetrahedral pattern.
Water is a very important part of the human body. Not only is it something that hydrates us, but it is all over the inside of our body. Without it, we couldn’t live more than five days at most. Blood is more than eighty percent water. More than thirty percent of our bones are made up with water as well. Water does lots of work for our bodies, as it distributes and carries the nutrients that are needed to cells. Examples include glucose or minerals.
In conclusion, the role of water plays an amazingly complex and vital role in the
Drinking water is one of our basic needs in order to survive, therefore the water that we drink and cook with must be of a high quality, and filtered of any harmful contaminants.
Water is very important to have in your body. Water is in charge of transporting nutrients throughout your body, removing waste products, controlling out body temperature, etc.. Without water our body would compl...
Water is one of the most important substances on earth. All plants and animals must have water to survive. If there was no water there would be no life on earth. Water nourishes
“Drinking water is like washing out your insides. The water will cleanse the system, fill you up, decrease your caloric load and improve the function of all your tissues.” – Kevin R. Stone --
As the sustenance for all humankind, animals, plants and other living organisms, Water is the greatest natural resources on this planet and it is becoming scarcer and more of a necessity. Water is a basic need and not a want in the same way that without air to breathe, cannot sustain life. Safe, clean water and good sanitation is a right. Therefore, the right to safe, clean water means the right to life. According to United Nations human rights are rights inherent to all human beings, whatever our nationality, place of residence, sex, ethnic origin, color, religion, language or any other status. Based on UN definition I am confident to assert that safe, clean drinking water and good sanitation is a basic human
The Biological Importance of Water as a Solvent and as a Medium for Living Organisms
Water is an essential nutrient that our body requires every day. Without water human life cannot be sustained. Water deprivation kills faster than lack of any other nutrient. People do not think of water as a nutrient and don’t realize the important role of water in the body functions.
Water is the most vital part of life. Water is needed from humans, to plants and other organisms, and to do basically everything. Water allows our bodily functions to work and to remove waste from our bodies. Plants need water to grow, and humans need plants to gr...
Water is the most priceless resource on our planet. Billions of gallons flow through our rivers and lakes. Millions of gallons are consumed by humans each day. Our world’s surface is seventy percent water. With so much water around us, how can 1.1 billion people still lack access to clean water (Cooper, Water Shortages)? People are already using fifty four percent of all the freshwater available on this planet (Cooper, Water Shortages). We cannot afford to neglect something so essential to our very survival. We must defend our most important natural resource—water.
Water covers about seventy one percent of Earth’s surface. Earth is the only planet to have stable bodies of liquid water on its surface which is crucial for all known life forms. Water is a substance which acts as a solvent in which organic compounds can mix, and it is the substance which is thought to be necessary to facilitate the formation of life. There are many forms of water which include ice, liquid, and gas. Because water can exist as a gas, it can be stored in the atmosphere and be delivered as precipitate. Water also helps regulate the climat...
