Photosynthesis. Using the sun�s energy green plants convert carbon dioxide and water into simple sugars and oxygen. Along with carbon dioxide, plants also need water, which is gathered by the plant�s roots, to make food through the process of photosynthesis. The stomata allows oxygen to be released through this process. This oxygen is an important exchange for all living things. Plants take in the carbon dioxide and give off the oxygen that we need in order to breathe.
no
nobody knows
Oxygen
Flowers do not give out oxygen, the green parts of a plant give out oxygen when the are engaged in photosynthesis.
oxygen
yes it dose
That is a parasitic plant. An example is cuscuta
Sponges are considered ANIMAL life not plant life. Therefore they do not give off oxygen, they consume it.
Plant cells can give off oxygen when photosynthesis occurs. They give out carbon dioxide when they respire when there is no light available.
I think when they receive carbon dioxide
The way to improve oxygen in the air is by increasing life that give off oxygen as a byproduct such as plant life. Animals use oxygen and give off carbon-dioxide which is used by plants which in turn releases oxygen in the air.
The trees absorb all the carbon dioxide and give off oxygen, the opposite of us.through the stem roots
