A water molecule falls on a chlorophyl molecule in a leaf. The Oxygen lies holding its two hydrogen atoms apart. A photon of light hits the electron holding one of the hydrogen atoms to the oxygen atom and it lets go. The chlorophyl molecule passes that hydrogen atom to another molecule. Then another photon of light hits the electron holding the other hydrogen atom to the oxygen atom and it lets go and the chlorophyl molecule passes that hydrogen atom to yet another molecule. At that point the chlorophyl molecule lets go of the oxygen atom. It meets up with an oxygen atom from another chlorophyl molecule. The two get together and leave the leaf.

∙ 15y agoGreen plants perform photosynthesis. Photosynthesis is the process by which they make their food, glucose. It is performed by reacting Carbon Dioxide, which the plant gets from the air, and water, which the plant gets from the soil (through its roots) using energy captured from sunlight. The energy is captured by the green pigment called chlorophyll, found in the plant's leaves. This gives the plant its green color. As a by-product of the reaction, oxygen is produced. the easiest way to explain it is to relate it to humans. we inhale air (02) through chemical reactions in our body which make us exhale (C02) which is exactly what in general all plants whether green or not, need. they will inhale C02 (Carbon dioxide) and through their chemical reactions exhale (02). their appearance is green through this reaction just like blood in the blood stream is actually clear but exposed to air turns red.

Do plants need carbon dioxide to grow?
yes if not then they will die n we need the plants because they give us oxygen
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.
Why are the plants useful to us?
Plants and us Plants are our food, they improve our air and they are used to make many things that we need such as medicines, clothes and paper. Trees are cut down and the timber used to build houses and furniture. Plants are useful to us in many ways. We need oxygen in the air we breathe. Plants take in the carbon dioxide gas that we breathe out and turn it into oxygen. Plants keep the air we breathe stocked full of oxygen. Plants are food for us. They give the us the vitamins and minerals we need to grow and stay healthy. =) ~
Do plants give oxygen off when using photosynthesis?
Yes plants give out oxygen during photosynthesis but only in the morning . At night when there is no sunlight they use the oxygen to make their food .
Do plants give humans oxygen?
yes, through photosynthesis Humans, in return, give off carbon dioxide to the plants, which they exhale after breathing the oxygen.
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.
What 5 example of what plants give us?
plants give us oxygen
Importance of plants?
plants give us oxygen and take carbondioxide
How plants are useful?
They give us oxygen, and help us to stay alive without plants we wouldnt be alive
What do the plants give us?
plant give us air or oxygen in scientific called
What helps us live?
The oxygen that plants give us and our lungs
What is interesting about plants?
plants give us oxygen and are a great source of nutrients
What do plants and trees have in common?
They both give us oxygen.
Why are plants important to grasslands?
grass important because it is a plant and gives us us oxygen
What do you have in common with plants?
we need water to survive like plants do. they give us oxygen we give them carbon dioxide.
How are oxygen and carbon dioxide exchanged between the veins and arteries?
Plants give us oxygen we give them carbon dioxide.
What do plants give us and what do you give them?
Plants are used for many things, including oxygen, food, medicine, and clothing. Shelter, oil, gas, wood, building materials, and water are also things that plants give the world.
