Detailed explanation-1: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.
Detailed explanation-2: -All plants give out oxygen during day and carbon dioxide during night.
Detailed explanation-3: -Plants take in CO2 through small cellular pores called stomata in the leaves during the day. During respiration (oxidation of stored sugars in plants producing energy and CO 2) plants take in oxygen (O2) and give off CO 2, which complements photosynthesis when plants take in CO 2 and give off O2.
Detailed explanation-4: -Plants release oxygen during the day in the presence of natural light through the process of photosynthesis. While at night, the plants uptake oxygen and release carbon dioxide, which is called respiration.
Detailed explanation-5: -Final answer: The part of the plant that takes in carbon dioxide from the air for photosynthesis is the stomata.
