Because in day we require more oxygen so they respire oxygen and in night we don't need much oxygen because while sleeping our body parts don't have to work much! Its a life cycle of God (Allah)
Plants continue to create Carbon Dioxide at Night.
Plants continue to create Carbon Dioxide at Night.
Carbon dioxide is absorbed by plants during the day through the process of photosynthesis. This is because plants use sunlight to convert carbon dioxide into sugars for growth and energy production. At night, plants respire and release some carbon dioxide back into the atmosphere.
Plants use carbon dioxide in the daytime as part of photosynthesis which occurs in the chloroplast. They use the CO2 and make sugars. People breath in oxygen and breath out carbon dioxide, plants do the opposite. They breath in carbon dioxide and breath out oxygen.One small "technical" detail that should be mentioned. Plants really don't breath, they respire. People breath.So, at the night, the plant cells respire more than they photosynthesise, so they get rid of more carbon dioxide than oxygen.
Plants don't exactly "trap" carbon dioxide, they diffuse carbon dioxide into their leaves through tiny holes called stomata. No, at night plants do not photosynthesize (because they need light to do so) so they have no need for carbon dioxide. Instead, as they still need to respire, they produce carbon dioxide as a waste product from respiration.
Mostly during night
Plants take in carbon dioxide during the day and release oxygen through photosynthesis. At night, plants do not photosynthesize and instead undergo respiration, where they take in oxygen and release carbon dioxide.
In general, plants either produce oxygen or produce carbon dioxide, but not both at the same time. During the daytime plants use sunlight (or other sources of light) to support photosynthesis where carbon dioxide is taken in and oxygen is generated. At night (or when it is dark) plants take in oxygen and generate carbon dioxide.
oxygen in morning and carbon dioxide in night.
respiration
Plants release carbon dioxide during respiration, which occurs both day and night. In the presence of sunlight, plants undergo photosynthesis, where they absorb carbon dioxide and release oxygen. The amount of oxygen released during photosynthesis is usually more than the carbon dioxide released during respiration, so there should not be a significant reduction in oxygen levels in a bedroom at night due to plants.
do plants switch how they use oxygen day and night?
