Final answer:
Plant cells both produce and consume CO2 and O2 through photosynthesis and respiration. This makes the provided statement about plant cells false, as they do produce O2 along with CO2 in a cyclic process.
Step-by-step explanation:
The statement 'plant cells produce CO2 but they do not produce O2' is False. In actuality, plant cells both produce and consume CO2 and O2 in a continuous cycle of photosynthesis and respiration.
During photosynthesis, plants consume carbon dioxide (CO2) and water to produce glucose and oxygen (O2). Conversely, in the process of respiration, plants consume O2 and glucose (produced during photosynthesis) to produce CO2 and energy.
