In plants, water helps transport nutrients into their bodies.Water in the soil has some solutes dissolved in it, such as mineral ions (nitrate, phosphate, magnesium).Tags: Syracuse Common App Supplement EssaysEssays For The GedSmu Doctoral Dissertation CompetitionWrite An Essay My First Day At SchoolCollege Scholarships Without EssaysUc College Application Essay Prompt 2013
The energy stored in organic molecules by photosynthesizers is the fuel of life for most living things and the oxygen released during photosynthesis makes cellular respiration—and therefore life—possible on earth.
Biological importance of water Water is essential to every living organisms.
Taking another example in animals, water is needed as reactant for hydrolytic reactions.
In the digestion of proteins, carbohydrates and fats, hydrolysis is required for their break down during the chemical digestion process.
The most common and critical type of photosynthesis takes place in chlorophyll‐containing plants, algae, and cyanobacteria.
These organisms capture radiant energy of the sun and, by utilizing carbon dioxide and water, convert it to chemical energy stored in molecules of carbohydrates. The generalized equation is: The other photosynthesizers are green and purple bacteria, which convert light energy to chemical energy, but use other raw materials and pigments in an oxygen‐free ( anaerobic) environment to make carbohydrates. A generalized equation for Photosynthesis is the single most important process on earth, for without it neither plants nor animals (including humans) could survive.Water is a major component of cells, it takes up around 70% to 95% of mass of the cell.Water possesses unique properties, for instance, high specific heat capacity, solvent properties, high incidence of hydrogen bonding and low viscosity. These characteristics cause water to become biologically important to all living organisms.Take respiration process as an example, in which glucose is metabolized, it has to first dissolve in water because all enzyme reactions have to be carried out in solution.Temperature control Due to the hydrogen bonding between molecules, water has a high latent heat of vaporization. When surrounding temperature is higher than body temperature, the body begins to sweat.As water does not heat up or cool down easily, the temperature of water does not fluctuate much.Thus, body temperature of species can be kept constant.However, the concentration of ions in soil water is much lower than that inside root hair cell, so soil water has a higher water potential.This allows water to enter root hair cell by osmosis, so minerals can be taken by plants for growth.In the simple example of the oxygen cycle shown below, you can see how oxygen is used and cycled by plants and animals.Plants are the main creators of oxygen in the atmosphere through the process of photosynthesis.
