Occurs in the absence of O2

It is common in higher plants

Detailed explanation-1: -So, the correct answer is ‘CO2 is given out’.
Detailed explanation-2: -Plant cells do not have mitochondria and therefore cannot respire using aerobic respiration. Anaerobic respiration occurs in the cytoplasm, therefore plants do experience anaerobic respiration.
Detailed explanation-3: -Aerobic respiration uses the oxygen gathered during the process of breathing to breakdown glucose (sugars) from food to carbon dioxide, water and energy.
Detailed explanation-4: -Anaerobic respiration is a type of cellular respiration where respiration takes place in the absence of oxygen. The end product of anaerobic respiration in plants is ethanol. At the same time, the end product of anaerobic respiration in animals is lactic acid.
