How does plants provide us with Oxygen?
Using energy and sunlight, it converts carbon dioxide & H2O into carbohydrates and oxygen called Photosynthesis
plants need to break down carbohydrates into energy. Oxygen is required to do this.
Plants hold on to a small amount of the oxygen they produced in photosynthesis and use that oxygen to break down carbohydrates to give them energy.
in order to maintain their metabolism and continue respiration at night, plants must absorb oxygen from the air and give off carbon dioxide.
plants use the carbon dioxide that we exhale along with water and sunlight to make sugar and oxygen (this is photosynthesis). This oxygen that they produce is released into the air, which we need to survive.
importance of oxygen for plants
Plants need oxygen to breathe and for cellular respiration. This is particularly important for the roots.
Specialised plant tissue in roots, called aerenchyma, create air gaps for oxygen and other gases.
Importance of oxygen for humans
Unhealthy or weak cells due to improper metabolism lose their natural immunity and are thus susceptible to viruses and lead the way to all kinds of serious health problems.
destroys also the harmful bacteria in our bodies without affecting the beneficial bacteria that we need.
