Question

Why do plant respire all day and night?

Answer 1

They need to respire virtually all the time in order to supply their energy needs. They are not able to use the ATP generated in photosynthesis for these purposes..

Answer 2

• As we know that the Plants are no exception.
• They need to respire virtually all the time in order to supply their energy needs.
• So Often, the respiration is masked by the fact that photosynthesis produces oxygen faster than respiration takes it up and photosynthesis uses carbon dioxide faster than respiration produces it.
• And plants respire all day and night or only during the day The process of photosynthesis requires sunlight.
• That's why it only occurs during the day. However, respiration does not require sunlight. It occurs during the day as well as the night.
• So, plants respire all day and all night or only in the night Plants respire all the time, whether it is dark or light.
• As we know that They photosynthesize only when they are in the light.
