∙ 15y agoOxygen is waste product of plant respiration in light as Carbon dioxide and water are combined to make sugars and other carbohydrates like starch and cellulose (wood) The normal formula you find in textbooks is 6 CO2 + 6 H20 ---> C6H1206 + 6O2 that is 6 molecules of carbon dioxide + 6 of water + sunlight go to 1 molecule of glucose and 6 molecules of oxygen. The glucose is then used to make things like starch and cellulose.

∙ 11y ago1. Because electrons need to transfering energy is obtained by photolysis of water. This produces oxygen. 2H2O-->O2+4H+ +2e
2. The first step of photosynthesis is related to the photolysis of water and O2 is released as bye product of photosynthesis
Anna Mbango
During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

∙ 14y agoOxygen is given off by plants from the product of photosynthesis.
6CO2 + 6H20 ---> C6H12O6 + 6O2
Carbon dioxide + Water + Sunlight produces Sugar + Oxygen

Which plants give oxygen all the time?
in the day, the plant will give out oxygen and take in carbon dioxide, but at night they take in oxygen and gives out carbon dioxide :)
Why do plants give out carbon dioxide in the dark and oxygen in the light and can this reduce oxygen in the bedroom at night?
Simple answer is, plants breath like any other organism, by day they give out oxygen and at night give out carbon dioxide, ie humans breath in oxygen and exhale carbon dioxide
How do green vegetation help to increase the quantity of oxygen in the atmosphere?
green vegetation are plants and of course plants give out oxygen and take our carbondioxide
Oxygen is added to an ecosysem by?
Oxygen is given off by plants as they absorb carbon dioxide. It's like how animals breathe in oxygen and breathe out carbon dioxide, except plants absorb carbon dioxide and give off oxygen.
What do plants give off as a waste product but they need carbon dioxide to survive?
When they take in the Carbon Dioxide they release Oxygen, Oxygen is also a byproduct waste of photosynthesis which plants do use.
What do plants give us back when you give them oxygen?
Plants give us oxygen and when we breathe it in we exhale carbon dioxide.
Which living things give off oxygen?
Most leafy plants and trees give off oxygen
What do plants give to the atmosphere?
Plants produce oxygen.
Importance of plants?
plants give us oxygen and take carbondioxide
What do plants give animals?
plants give animals oxygen and food.
What 5 example of what plants give us?
plants give us oxygen
Why is it important that plants give off oxygen during photosynthesis?
Why is it important that plants give off oxygen during photosynthesis
What do plants give off?
Oxygen
What do plants give off that animals need?
The animals need the oxygen that plants release.
What do plants give living things?
Plants give living things oxygen to live.
What gas does plants give off in the light?
Plants produce oxygen when exposed to light. They do this by the process of photosynthesis. The oxygen comes from the splitting of water molecules to produce hydrogen ions and the oxygen is expelled as a waste product.
Do animals and plants have blood to carry oxygen?
Well animals do but plants don't. Plants don't actually really use oxygen- they give it out. They use the sunlight and Carbon Dioxide in photosynthesis and the by-product (what they give out) of this is Oxygen.
