HYDROPONICS: Why do plants grow better in water with oxygen than non oxygenated water?????????

Answer 1

like several others have said, plants need oxygen to perform cellular respiration. even if they are able to capture the oxygen evolved from photosynthesis they still need oxygen when they are not preforming photosynthesis.
water contains very little free oxygen. the saturation point is only 10mg/l and the water the plant is in probably is not at saturation unless it is being oxygenated. water conditions can easily become anaerobic and plants are obligate aerobes.
even if only the roots are submerged they still need to have gas exchange, especially oxygen (most roots are not photosynthetic although some orchid roots are) and CO2.
so oxygenating the water will make sure that the plant is exposed to as much oxygen as possible to satisfy its aerobic requirements.

Answer 2

Believe it or not, plants have to breathe as well as anything else. Water can literally drown a plant. That is why the water needs to be oxygenated.

Answer 3

Hydroponics is crop production with mineral nutrient solutions instead of soil containing silt and clay. Terrestrial plants may be grown with their roots in the mineral nutrient solution only or in an inert medium, such as perlite, gravel or rockwool. A variety of techniques exist.

Plant physiology researchers discovered in the 1800s that plants absorb essential mineral nutrients as inorganic ions in water. In natural conditions, soil acts as a mineral nutrient reservoir but the soil itself is not essential to plant growth. When the mineral nutrients in the soil dissolve in water, plant roots are able to absorb them. When the required mineral nutrients are introduced into a plant's water supply artificially, soil is no longer required for the plant to thrive. Almost any terrestrial plant will grow with hydroponics, but some will do better than others. It is also very easy to do; the activity is often undertaken by very young children with such plants as watercress. Hydroponics is also a standard technique in biology research and teaching and a popular hobby.

Oxygenated Water



The quality of the water we drink has an important impact on our health. Technology has come a long way providing us with the means to improve the quality of our water.

Anthropological studies on populations where people live very long and healthy lives have shown that the common denominator of these groups was the high quality of water that they drank every day. The source of this water was high up in the mountains where the mineral content was colloidal, and the water was “highly energized.”

Technology has been developed so that you can change your own drinking water in your home to be more oxygenated and energetic.

One of the best devices is the Antioxidant Water Ionizer. It first filters the water of impurities, then it uses ionization to make the water alkaline. When you drink it, your body becomes more alkaline so your blood is able to absorb much more oxygen from the air you breathe. You can also buy Alkazone drops to alkalize your water. Just put several drops in your glass of water.

The E-Water Machine also uses ionization to reduce the cluster sizes of the water. Water molecules stick together in strands of about 12 molecules, so when you reduce these clusters in half, the water becomes more absorbable by the cells to hydrate you faster. It is very useful for cellular detox. You can also use Crystal Energy drops to reduce the cluster size of your water just by adding several drops to your glass.

The Oxygenated Water Cooler adds oxygen to your drinking water every 15 minutes. It is very convenient in the workplace, and, by drinking water with more oxygen, you will have more energy throughout the day. The Water Ozonator also adds more oxygen to your water. All you do is put the dispenser in your glass of water, turn it on, and it is ready in five minutes.

Willard water is another additive which adds colloidal minerals and enzymes to your water. These minerals replenish your body’s electrolytes to give you more cellular energy.


The Non-Mineral Nutrients are hydrogen (H), oxygen (O), & carbon (C).

These nutrients are found in the air and water.
In a process called photosynthesis, plants use energy from the sun to change carbon dioxide (CO2 - carbon and oxygen) and water (H2O- hydrogen and oxygen) into starches and sugars. These starches and sugars are the plant's food.

There were some changes in the chemical water characteristics due to the artificial oxygenation. Oxygenation prevented O2 depletion throughout the treated water columns, whereas the hypolimnion was anoxic at the non-oxygenated sites. The lower PTOT concentration in the oxygenated waters could well result from increased absorption of dissolved iron and P to the more aerobic sediment. The decrease in the availability of P would further limit the primary production during the early summer. The lower hypolimnetic NTOT concentrations in the oxygenated water columns could reflect accelerated mineralization of ON. However, this could not be seen in the ON concentrations, which were rather similar in the non-oxygenated and oxygenated water columns. Nevertheless, the extent of nitrification seemed to be increased by the oxygenation

Answer 4

Plants perform respiration too. They need oxygen for respiration which is how all that energy they take from sunlight is converted into energy.

Answer 5

Roots require oxygen for respiration so they grow better in oxgenated water,

Answer 6

think cellular respiration

no, wait...

plants get oxygen from photosynthesis, right? so maybe it's not cellular respiration

Answer 7

they need oxygen. duh.
