Oxygen 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.
1. 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
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.
Oxygen is given off by plants from the product of photosynthesis.
6CO2 + 6H20 ---> C6H12O6 + 6O2
Carbon dioxide + Water + Sunlight produces Sugar + Oxygen
Photosynthesis
plants need oxygen to breathe at night
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 :)
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
green vegetation are plants and of course plants give out oxygen and take our carbondioxide
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.
When they take in the Carbon Dioxide they release Oxygen, Oxygen is also a byproduct waste of photosynthesis which plants do use.
Plants give us oxygen and when we breathe it in we exhale carbon dioxide.
Most leafy plants and trees give off oxygen
Plants produce oxygen.
plants give us oxygen and take carbondioxide
Why is it important that plants give off oxygen during photosynthesis
plants give us oxygen
plants give animals oxygen and food.
Oxygen
The animals need the oxygen that plants release.
Plants give living things oxygen to live.
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.
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.
