photosynthesis
Most leafy plants and trees give off oxygen
Plants produce oxygen.
Why is it important that plants give off oxygen during photosynthesis
plants give us oxygen
plants give us oxygen and take carbondioxide
Plants give out oxygen (from the breakdown of water) and take in carbon dioxide, which they use to form carbohydrates in the process of photosynthesis.However, at night and in darker conditions, plants still need energy, and use cellular respiration as animals do, taking in some oxygen and releasing carbon dioxide. This is normally much less chemical activity than photosynthesis, so green plants release much more oxygen than they use.
Oxygen
Plants give living things oxygen to live.
The animals need the oxygen that plants release.
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.
Plants give out oxygen which we take in and then we give out carbon dioxide which the plants take in
