Question

Why plants take carbon-dioxide during day and oxygen at night?

Answer 1

$\huge{\mathbb{\red{ANSWER}}}$

Plants give out carbon dioxide not only at night but during the day too. It happens because of the process of respiration in which plants take in oxygen and give out carbon dioxide. As soon as the sun rises another process called photosynthesis starts, in which carbon dioxide is taken in and oxygen is given out.
