Does producing oxygen as a by-product of photosynthesis mean that plants can live in anoxic soil Explain your answer?

The oxygen is liberated into the atmosphere which doesn't help the roots which are usually in soil or a soil mixture. The roots (specifically, root hairs) need oxygen to survive.
Soil lacking enough air spaces, like highly packed-down soil or clay , will not allow the roots to respire regardless of how much oxygen is being released by the leaves.

What is the difference between anoxic and anaerobic condition?
Anaerobic = total absence of free oxygen (O2) or bound oxygen (NO2, NO3) Anoxic = absence of free oxygen, but presence of bound oxygen.
When did the earth go from anoxic to oxic?
around about 2000 million years ago
What term is used to describe water with too little oxygen to support life?
Anoxic.
How can you distinguish between a brain injury caused by hyponatremia and a brain injury caused by anoxia or hypothermia or bypass?
Hyponatremia occurs when there is a serious deficiency of sodium in the blood. Blood tests would be able to detect whether this is the problem.Anoxic brain injury is the result of a major lack of oxygen to the brain. When the brain doesn't receive proper amounts of glucose and oxygen, nerves in the cortex where cells originate are damaged. It takes about five minutes for lack of oxygen to permanently damage the brain. Anoxic brain injury causes diffuse damage, meaning that it causes damage throughout the brain. Causes of Anoxic Brain Injury There are three types of anoxic brain injury. Anemic anoxia is a result of blood that doesn't carry enough oxygen. Toxic anoxia is caused by toxins that block oxygen in the blood from being used. Anoxic anoxia occurs when no oxygen is supplied to the brain. Common causes of all three types include: * Respiratory arrest * Drowning * Heart attack * Carbon monoxide inhalation * Poisoning Symptoms of Anoxic Brain Injury While symptoms will vary based upon the area of the brain that's affected, common signs of anoxic brain injury include: * Cognitive issues * Weakness in arms and legs * Lack of coordination; abnormal movements * Visual problems * Emotional and behavioral problems Prognosis for Anoxic Brain Injury Degree and rate of recovery is highly dependent upon individual circumstances. The amount of time spent unconscious or in a coma, as well as how much is recovered within the first month, are good indicators of long-term recovery.http://www.brainandspinalcord.org/traumatic-brain-injury-types/anoxic-brain-injury/index.html
What is phenol oxidases?
Phenol Oxidases are enzymes that oxidize phenolic compounds to quinones. An example of this involves the brown coloring that soon takes place when cutting into a potato or apple as the fruit or vegatable is exposed to the open air. It is commonly observed in apple, potatoes, bananas and avocado. This enzyme can be denaturalized with cold water, anoxic environments (no oxygen) or by acid addtion like lemon.
Does pleurococcus photosynthesise?
yes, anoxic photosynthesis
Can plants live in anoxic soil?
Yes plants can live in anoxic soil. an example of a plant that can live in anoxic soil is the mangrove. A mangrove can live in anoxic soil because of little arial roots called pnuematophores that are not submerged by water during the day, this allows them to draw oxygen into the underground root system.
What rhymes with anoxic?
Toxic.
Why was the change from anoxic to oxic atmosphere significant?
Because it allowed procariote autotroph cells (non-bound organelle cells which produce their own food) to develop because they now had oxygen available to perform photosynthesis.
The difference between oxic and anoxic soil?
Soil that contains oxygen is known as oxic soil. On other hand soil which lacks the oxygen is known as anoxic soil
What are the main causes for anoxic brain injury?
The main causes for anoxic brain injury are lack of oxygen to the brain. This can be caused due to drowning, suffocation, shock or autoerotic asphyxiation.
What is without oxygen?
The terms for without oxygen are anaerobic or anoxic.
What is Stagnation deposits?
decreased microbial decomposition, often anoxic.
What is the difference between anoxic and anaerobic condition?
Anaerobic = total absence of free oxygen (O2) or bound oxygen (NO2, NO3) Anoxic = absence of free oxygen, but presence of bound oxygen.
When did the earth go from anoxic to oxic?

What term is used to describe water with too little oxygen to support life?
Anoxic.
Do all of the steps of cellular respiration need oxygen?
No; and those that do not are called anoxic steps.
