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.
I think when they receive carbon dioxide
Plant cells can give off oxygen when photosynthesis occurs. They give out carbon dioxide when they respire when there is no light available.
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
No. Animal cells use Oxygen and give off carbon dioxide as a waste product. Plant cells use carbon dioxide and give off oxygen.
