Why is water important to living things?

Water is the medium via which all important vitamins and minerals are conveyed in living organisms’ bodies (owing to its ability to dissolve a wide range of substances) and due to which water is the most element on earth.

It is also essential for the function of enzymes in living organisms.For example, breaks down sodium bicarbonate released by the pancreas into ions, making the medium alkaline enough for the enzymes to act.

It aids in the maintenance of body temperatures in both plants and animals. Animals lose it through perspiration (sweating) while plants lose it through transpiration to reduce body temperature.

It may be transferred from the roots of trees to any other part of the tree because it can ascend in capillary tubes without any external assistance.

It is an essential component of photosynthesis. Autotrophic plants would be unable to manufacture their own nourishment without it.

It provides a home to more than half of all life on Earth.

Water is important for the survival of all living beings.For example, is required by all oxygen-dependent species to aid in the respiration process. They useful to creatures in a variety of ways. It is used in four ways: as a solvent, as a temperature buffer, as a metabolite, and as a living environment.

As a Solvent:


Because of the molecular interactions , water attracts both positive and negative ions. As a result, positive ions are drawn to the oxygen , whereas negative ions are drawn to the hydrogen. This helps them to dissolve chemicals essential for survival, such as glucose derived from food.

As a Metabolite:


The totality of all chemical reactions within an organism is referred to as metabolism.Water is important because it is a metabolite, or a molecule that participates in processes. In this way, it’s essential for the survival of both plants and animals.

It aids photosynthesis in plants, which is the process through which plants turn sunlight into food. They separates into hydrogen and oxygen atoms during the first stage of photosynthesis. While oxygen is discharged into the environment, hydrogen is used in the remaining chemical reaction to make glucose to nourish the plant.

Temperature Buffering:


Water is important during temperature regulation, for chemical reactions that are critical to cellular activity, like respiration . Enzymes, which are proteins that act as catalysts to initiate chemical processes, are heat-sensitive and will only function at certain temperatures.

It has a high specific heat capacity, which means it takes a lot of heat to warm it up. As a result, absorbs a lot of heat while keeping the organism’s temperature constant. This keeps enzymes from overheating and malfunctioning.

Water as a Living Medium:


Aqua-based species, such as fish, require it to breathe by directly inhaling 3oxygen dissolved . They would suffocate if they were unable to acquire oxygen due to a lack of it.

It also serves to insulate these species’ dwelling environments.

Water’s Importance in Human Beings:


Inadequate fluid content in the human body causes severe dehydration, which is frequently followed with kidney failure, convulsions, and brain enlargement.

It aids in the distribution of oxygen throughout the body.

It also plays an important part in food digestion.

It is an essential component of saliva, which aids in the digestion of meals.

It is required for waste excretion in the human body. Inadequate  levels in the body can put additional strain on the kidneys, leading to the production of kidney stones.
