Oxygen
Plants release oxygen as a waste gas.
a waste gas createdby cells. Used by plants to survive
Plants need carbon dioxide in order to make their own food.
The waste gas produced by plants as they respire is oxygen. This is why plants are very important to the earth. Without plants, there probably would not be enough oxygen in the air for all to breathe.
Plants, Animals, and Bacteria
Depends on what reaction you're considering. For plants Oxygen is a waste gas, for animals its CO2, in an oil well it might be methane.
Oxygen
Plants give off waste as a products through photosynthesis. These wastes include but are not limited to oxygen the gas.
The waste gas released by green plants during photosynthesis is oxygen, which is crucial for the survival of most living organisms, including humans. We rely on plants to produce oxygen through photosynthesis, which we breathe in to support our respiration and overall metabolic processes.
Oxygen
A plant takes in carbon dioxide stores the carbon then releases oxygen as a waste gas.
Plants use carbon dioxide gas in the process of photosynthesis, and exhale oxygen gas as waste.
