I think when they receive carbon dioxide
Most leafy plants and trees give off oxygen
Plants produce oxygen.
plants give us oxygen
plants give us oxygen and take carbondioxide
Why is it important that plants give off oxygen during photosynthesis
Oxygen
The animals need the oxygen that plants release.
Plants give living things oxygen to live.
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.
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.
Plants give out oxygen which we take in and then we give out carbon dioxide which the plants take in
Plants take in Carbon Dioxide and give out Oxygen.
