Oxygen is a by-product of using sunlight to convert carbon dioxide to glucose. It takes in oxygen at night though which is because there is no sunlight at night and to replace this, the plants uses O2.
During cellular respiration, plants take in carbon dioxide and give off oxygen while animals take in oxygen and give off carbon dioxide.Sorry if I didn't answer your question sufficiently!
plants during photosynthesis take in carbon dioxide and give out oxygen while animals during respiration breathe in oxygen and breathe out carbon dioxide making a complete continuous cycle.
In general outline, photosynthesis is the opposite of cellular respiration. CO2+ H2O+sunlight ----> O2 + H2O +carbohydrates.It uses carbon dioxide and the energy from sunlight to make carbohydrates and oxygen (a waste product from plants).
Why is it important that plants give off oxygen during photosynthesis
Respiration by plants is the same as that of animals, and is indeed a reverse of the equation for photosynthesis: Photosynthesis - carbon dioxide + water ----- glucose + oxygen Respiration - glucose + oxygen ----- carbon dioxide + water (+ energy, obviously)
Green plants take in carbon dioxide during photosynthesis and give out oxygen. While respiration, all living organisms take in oxygen and carbon dioxide and then give out carbon dioxide.
when the plant does photosynthesis, there r two things produced. These are oxygen and water. during cell respiration, plants take in oxygen and give out carbon-di-oxide sothe plant gives out more of oxygen and water and less of carbon-di-oxide.
Plants have two types of respiration arobic and anerobic Plants do not breathe like humans, although they respire. This is when they absorb oxygen from the air around them and in return, release Carbon Dioxide. This is different from photosynthesis where they release oxygen and take in carbon dioxide. They photosynthesise to produce glucose, and then respire to convert that glucose into energy. During the day, plants give out more oxygen, and during the night, plants give out more carbon dioxide.
trees do not give nitrogen..... nitrogen is a constituent of proteins, and plants do not consume proteins. also, there is no metabolic activity taking place in plants, so no nitrogen produced by plants.... it gives oxygen during photosynthesis, and carbon di oxide during respiration.. that's it....
Carbon dioxide + water + sunlight => photosynthesis => glucose + Oxygen
Respiration occurs in all living cells - days and nights (any time). Animals respire (breathe) taking in oxygen and exhaling carbon dioxide all the time. Plants - green plants - tend to take in carbon dioxide and give off oxygen during daylight hours, but reverse the process overnight.
Cellular Respiration is only in animals. Photosynthesis is in plants. To be precise, photosynthesis is in the mitochondria of organism like us, and respiration is in the leaves of plants. Photosynthesis and Respiration together are a cycle- plants give out oxygen and use carbon dioxide while we humans (and other organisms) use oxygen and give out carbon dioxide. I just just learned this in school. :)
