Mitochondria Cellular respiration is a set of metabolic reactions and processes that take place in the cell of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP) and release waste products. Cellular respiration breaks down glucose and releases carbon dioxide into the atmosphere. So, the correct answer is 'Mitochondria'.
All vascular plants have water-conducting tissue and are better adapted for life on land than the bryophytes; they are also characterized by a dominant sporophyte generation.
