How the Properties of Water are Related to Its Roles in Living Organisms and as a Living Environment for Living Organisms

Water is a medium for metabolic reactions and an important constituent of cells. In most plants and animals, it makes up about 65-95% of their mass. The water molecule is referred to as a dipole, a polar molecule, with a positive (hydrogen) and negative (oxygen) charge, separated by a very small distance. A molecule with a separated charge is polar. A hydrogen bond; the weak attractive force between a hydrogen atom with a partial positive (o+) charge and an atom with a partial negative charge (o-) oxygen can be formed between two atoms. Hydrogen bonds are weak, however in large quantities, like the large number present in water it makes the molecules difficult to separate and gives water a wide range of physical properties vital to life.

Fresh water is one of the basic needs and essentials of all living things. Although, we all utilize it differently, we use it in an everyday basis. Without water, it is simply said in five words that “there would be no life.”

Living things are mostly made of water because it possesses important elements that are necessary to sustain life in addition to refreshment and nourishment. For example, cells are made of 70-95% water and are surrounded by water as well. Water also helps fluidity in the body, with nearly 54% water in our blood. Our bodies are made of 75% water, making many functions such as the transportation of hormones, chemical messengers, and nutrients to vital organs dependent on water. In addition to human bodies, plants are also made out of water. Water is necessary to plant life because it helps with the germination of seeds, photosynthesis, the transportation of minerals and nutrients from soil to plants, and the structure of the plant to thrive and survive.

Water: a necessary facet to all living things. For animals, water can be a home or a drink. As for humans, the uses of water are endless. Not only do we use water as a beverage or washing clothes or dishes, but we also use water for toilets, various kinds of plumbing and other things that aren’t as easily identifiable. As of 2005, this 70% of our Earth has been manipulated and used for thermoelectric power (41.5%), irrigation (37%), domestic affairs (8.5%), public supply (5.4%), industry (5%) and aquaculture (2.6%).1 The importance of water is infinite, not only to our way of life, but also our lives. We need to drink water to ensure the health of individual cells of the body, lubricate joints, moisten mucous membranes of the organs and many other vital bodily functions.2 Not only do we expect the availability of water, but it is highly important to humans and all living things. Although it is such an integral part of our Earth, one may ask about some of its properties and characteristics.

Water is essential for life as we know it on earth. It is used by plants

The main focus for this lab is to determine why and how water is so essential to life. To begin with, water transports molecules around the body which is in fact very important because afterwards the body gets rid of any waste or toxins in which is unecessary for the body to keep. In addition, water keeps many ogranisms alive and growing, water can range in three different tempetures such as; solid, liquid and gas, in the end all of these occur on the earth. Waters scientific term is H2O which conclude; hydrogen and oxygen atoms, hydrogen is known to be a positive charge and oxygen has a negative charge and together end up having no charge, which makes the molecule polar. The purpose of this study is to dive deep and determine waters importance to life and why it is so essential.

Water and its properties are very essential for all living things. In fact, scientists are paying close attention to presence of liquid water on other planets in efforts to find extraterrestrial life in space. Water has properties that makes it a key role to sustain life 1. As it is a universal solvent, it acts as a medium for most biochemical reactions 2. Without water, it is impossible for a living thing to function. Zooming out, water is important in daily life as many aspects depend on water. Water is used for domestic and industrial purposes. On average, people in the United States drink 110 million gallon of water everyday 3. In total, 400 billion gallon of water is used in United states everyday 4.

The Importance Of Water To Living Organisms Water is normally the most abundant component of any living organism. As most human cells are approximately 80% water and 60% of the human body is made up of it, it is extremely important in many different ways to both the survival and the well being of living organisms. Evolutionists believe that life probably originated in water and even today thousands of organisms make their home in it. Water also provides the medium in which all biochemical reactions take place. The importance of water to living organisms originates from its many properties including its solvent properties, its high specific heat capacity, its high latent heat of vaporization,

Water is an important component to sustaining life. Water is used for many things. Along with sustaining homeostasis in living organisms, it is used for agriculture and hygiene practices. Without clean and fresh water, ecosystems and human life are threatened. Many people across the globe are either fighting for clean water or are using it in their everyday life. This lack of equal obtainment of water, is the number one thing effecting the world.

Chemistry of Life - Chapter 2: Focus on 1) the nature of the hydrogen bond; 2) properties of water essential to life; 3)

Our bodies are on average about 60% water, water is so important and we cannot live without it as it; regulates our body temperature, moves nutrients through cells, keeps our mucous membranes moist and flushes waste out of our bodies. In this assignment I am going to be describing the distribution and constituents of the body fluids and explain the functions of the constituents of the body fluids. This assignment is mainly about the importance of water and its role within the body and all of its distinctive properties.

Biological systems need water because it provides many functions. Water is a unique molecule that is known to mankind and it is also important to the biological systems. Water exists in three states of matter including solid, liquid, and gas. The solid phase of water is known as ice. Water is mainly a liquid at room temperature. Water at room temperature supplies an environment for organisms to live in as well as providing a liquid environment inside cells in order for them to live. The gaseous phase of water is known as water vapor. Water is made up of 2 basic components called Oxygen and Hydrogen. Water is known to be a polar covalent molecule and is the main indication of transportation of substance between cells and tissues. Water acts as a solvent for chemical reactions which helps transport dissolved compounds into and out of cells. Since water is ionized, it can be used for many functions such as transportation in the body, nutrients, sugar, and salt can be transported throughout the body through the bloodstream. Molecules such as glycogen are not soluble and cannot be transported therefore will used for storage. Water can also act as a base and an acid.

The amylase will digest the starch; thus, there will be no change in the color of the liquid inside, or outside, of the dialysis membrane because the Lugol’s reagent will not have surrounding starch to react with.

Water is a simple molecule created by two hydrogen bonds and one oxygen bond. Water’s formula is H2O because there are two hydrogen bonds and there is one oxygen bond. When these three bonds come together, they become strong and unbreakable. Water is very important. It is important to earth and to your body. Water covers 70% of earth’s surface and your body contains about 60% of water. Water is not just a liquid. Water can also be a solid or gas. Ice is water, but in the form of a solid and a gas is water, but in the form of vapor. Water’s state of matter can change easily due to a temperature increase or decrease. Changing water’s state of matter is a physical change, meaning it can be reversible. So, the objective of this lab is to see how temperature can change water’s state of matter.

Earth truly is an amazing planet, it host vasts amount of diverse species and variety of environments that makes life possible, livable and scientifically, the reason why we are here today. We, humans with our advancements in science and technology, have the ability to create genetic materials in replacement for natural ones, develop cure for diseases, learn and communicate with a touch of our finger tips, the capability to build complex air shuttles that can explore to outer space and soon to land and study a planet different from ours. As we gain more knowledge about life outside earth, one of the main elements scientist look for when examining and exploring a possible substitute for our dear planets is water. “Water is life. It's the briny broth of our origins, the pounding circulatory system of the world, a precarious molecular edge on which we survive. It makes up two-thirds of our bodies, just like the map of the world; our vital fluids are saline, like the ocean. The apple doesn't fall far from the tree.” (Water Is Life, 2017) For this reason, the element that I selected from the material cycle that we have studied is water.
