overestimate the importance of plants in nature and human life is impossible.Through the process of photosynthesis, they are the main producers of a huge amount of organic matter in fresh and salt waters.Special attention is given by the fact that the algae produce intense oxygen in the water, so necessary for river and marine life.Man has long appreciated the plants and found them used in many industries and in agriculture.
value of algae in nature and human life
Perhaps the most important function, which is performed absolutely all kinds of algae, is the absorption of water from the carbon dioxide.In exchange, they produce oxygen, without which it is impossible to imagine the life of modern plants and animals.No less important part of algae in the circulation of substances on the planet.Its cyclical nature allows you to be all kinds of living creatures on the earth has been for thousands of years.In addition, algae - the main source of organic matter in water bodies, which are an excellent food source.A huge number of animals depend on it.Equally important evolutionary significance of algae.They are greatly influenced not only the composition of Earth's atmosphere, but also on the formation of its relief.In addition, these plant organisms (both single-celled and multicellular) play an important role in the self-purification of rivers, lakes and ponds, as well as waste water.Algae are unicellular especially their representatives, are an excellent indicator of salinity and water pollution.However, they are found not only in water but also in the soil.By participating in the cycle of silicon and calcium, they are actively enrich the ground these components.
value of seaweed in agriculture
great importance of algae in nature and human life due to their ability to produce organic matter.Therefore, they are widely used in cosmetics, food and pharmaceutical industries.But many more are used in agriculture.In developed countries, on the basis of algae produced fertilizer.If they spray seedlings of tomatoes, peppers, eggplant, melons and gourds, then they not only grow faster but also gives a large harvest.In addition to vegetable growing, algae have penetrated and livestock.The cows, geese, chickens, ducks become more productive especially when balanced diet.The food animals are organic agricultural ingredients seaweed.
value of algae in the food industry
annually on all continents of the world people eat several billion tons of processed seaweed.First of all we are talking about seaweed.It belongs to brown algae.It contains a huge amount of nutrients and, importantly, the nutrients.This compound and iodine, and calcium, which is essential for normal metabolism.The value of algae in nature and human life is enormous.Cultivation of marine and freshwater crops gives very encouraging results.They are increasingly used in the food industry.For example, Japanese cuisine uses seaweed flour when baking bread.And this is the main product on the table in every family.Algae added to puddings, cakes and even ice cream.Recently, no less important application in their preservation.In many countries, every year offers more cafes where you can enjoy a variety of dishes exclusively from algae.
unicellular algae and their significance in space
Strangely enough, but it is a simple unicellular alga Chlorella has an enormous role in modern astronautics.It is able to develop a large amount of oxygen.In this she concede almost all types of plants.Also important the fact that it has a microscopic size, and therefore do not take up much space.She has a short growing season, and the process is very high rate of reproduction.All received chlorella biomass can be used for space stations, not only for the production of oxygen, but also as food.Its nutritional quality is really impressive.The protein content of Chlorella is not less than 50 per cent of the dry weight.Also contained in the algae necessary for human life amino acids and vitamins.All this makes the use of chlorella in space flights is very promising.
The use of algae in microbiology
great variety and importance of algae.They have been applied even in microbiology.From brown and red algae produce a substance agar.It is able to solidify at room temperature and gelatinize.It is his property and became the determining factor in choosing between gelatin and agar in the production of culture media for the cultivation of microorganisms.This material has good nutritional properties and does not melt in a thermostat.Therefore at present all artificial media prepared on the basis of agar.
use algae to clean wastewater
recently increased the value of algae in a person's life in the domestic sphere.They are cultivated in industrial waste waters, in order to activate the self-purification processes.In the future, excess organic matter will be used to produce methane, which is planned to be used in agricultural and industrial production.The best way to cope with pollution chlamydomonas.It is able to select from a water organic substance by cleaning.
