The Importance Of Water To Living Organisms Essay

As water molecules are dipoles, they attract/are attracted to ions in solution and therefore the water molecules cluster around the ions and separate them, thus dissolving the substance. It also dissolves other polar molecules as it can interact with the charged regions. These then dissolve in water so chemical reactions can take place. This property and being liquid over a wide range of temperatures, makes water ideal for acting as a medium where these metabolic reactions can occur. Water also acts as a transport medium for example in animals, plasma transports dissolved substances and in plants, water transports minerals in the xylem, and sucrose and amino acids in the phloem. Non-polar molecules such as lipids do not dissolve in

The human body consists mostly of water, and is a major constituent to the human body and vital organs; of this 90% include blood plasma, lymph, urine, saliva, digestive juices, bile, cerebrospinal fluid and tissue fluid. Water enables substances to be transported throughout the body, red blood cells for example, as wells as supplying the medium required for metabolic reaction to take place (respiration). Without water the progression of these fluids would not be possible. Water is constantly being transported between the fluid compartments of

(Click Slide) Another unique property of water is its high specific heat capacity. Due to the strong hydrogen bonds that exist between water molecules, a lot of energy is needed to break down the bonds. As the Particle Theory states, particles move faster and further apart when heated. This is why water helps maintains a moderate temperature on Earth and different bodies of water, crucial for the survival of organisms.

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.

Added temperature furthermore drops the quantity of oxygen molecules, which is dissolved in the water. Water composed of two negatively charged oxygen atoms and one positively charged hydrogen. When the temperature is cooler these particles encompass less energy and there is less change that they get separated from each other. In contrast atomic particles are more energetic when the temperature is warmer ands so they will get separated from the hydrogen atom. So cold water holds more oxygen (Mallya 2007). Added temperature furthermore drops the quantity of oxygen molecules, which is dissolved in the water.

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

Water is one of the most important elements on Earth and also for our body. We need water to work and function properly and well. Without enough supply of water, our body will grind to a halt and collapse.

Water is essential for life on earth. Water is needed for growing food, keeping ourselves clean, generating power, controlling fire and most importantly to stay alive! This list is simply non-ending. This shows that water is an integral part of our daily life and we are heavily dependent on it.

Very recently, I watched a program on public television about freshwater. It really got me interested in thinking about how important water is to human survival. Fresh and clean water is vital to the very existence of the human race. Without it, all living things would die, including human beings. So how important is water to humans and why?

Ever since the beginning of time water has been important. Water has been important because it is one of the most abundant substance on Earth. Water is important because every living thing contains water, and every living thing must have water to function. Water is important whether it is e drunk a supper or if it is being used for survival in the desert. Water is important because it is required for man to live, breath and thrive on this planet. In the article, “How Much Water Do We Actually Need,” J. Lunn and R. Foxen state, “Water is an essential requirement for life- without water, humans can only survive for 2 to 3 days at the most”(336). In addition to water being essential for life, it also has many

Hydration with water and other water-based liquids is critical for survival and functioning of the body’s organs. Water is 60% of the total human body composition. Water is involved in the

Water is a vital nutrient needed for the survival of all species. One quality of water that was observed in this lab is known as the “hardness” of water. Hardness is caused by the presence of polyvalent cations that dissolve in the water as it moves through soil and rock.1 The main minerals that give water a hard quality are Ca2+ and Mg2+ therefore, a sample containing a large concentration of calcium and magnesium is considered hard while a sample containing little or no calcium and magnesium is considered soft.3

Clean water is a necessity to live well on our planet there for the teaching resource described here will be one that can show how our plants help keep our water clean, making the purification easier for human consumption, the container that holds the grass or plant life will drain water out that looks a lot clearer than the container with just dirt, showing just one of the ways of how important plants are to keeping us alive and healthy.
