If plants need oxygen for cellular respiration, then why do plants release oxygen into the atmosphere?

More oxygen is produced during photosynthesis than the plant needs for cellular respiration, so the plant needs to release the extra oxygen.
Plants need to collect more oxygen from the atmosphere because photosynthesis does not produce enough oxygen to meet their needs.
Plants need to release oxygen into the atmosphere so more carbon dioxide can enter the plant for photosynthesis.
Plants release oxygen into the atmosphere because the release of oxygen prevents the evaporation of water.

I'm a little confused on this, I was thinking A or C, but I could be totally wrong. Please help? thanks

Nevermind, it's A

The correct answer to your question is A: "More oxygen is produced during photosynthesis than the plant needs for cellular respiration, so the plant needs to release the extra oxygen."

Plants undergo a process called photosynthesis, which utilizes sunlight, water, and carbon dioxide to produce glucose (a form of energy) and oxygen. This process occurs in special organelles called chloroplasts, which are primarily found in the leaves of plants.

During photosynthesis, plants capture energy from sunlight and convert it into chemical energy in the form of glucose. In this process, they take in carbon dioxide from the atmosphere and release oxygen as a byproduct. The oxygen that is released by the plant is surplus, meaning the plant produces more oxygen than it requires for its own cellular respiration.

Cellular respiration, on the other hand, is the process by which plants (and all living organisms) use oxygen to break down glucose and convert it into energy for their cellular activities. Plants need oxygen for respiration, just like animals do.

So, in summary, plants release oxygen into the atmosphere because photosynthesis produces more oxygen than the plant needs for its own cellular respiration. This surplus oxygen is then released into the atmosphere, contributing to the oxygen content of our air and allowing other organisms, such as animals, to utilize it for their own respiration.

The correct answer is C: Plants need to release oxygen into the atmosphere so more carbon dioxide can enter the plant for photosynthesis.

During photosynthesis, plants use carbon dioxide, water, and sunlight to produce glucose and oxygen. The glucose is used as a source of energy for the plant, while the oxygen is a waste product. However, the plant also needs to continuously take in carbon dioxide to sustain photosynthesis. By releasing oxygen into the atmosphere, plants create a favorable concentration gradient for the diffusion of carbon dioxide into their leaves. This allows plants to continue performing photosynthesis and produce more glucose for growth and energy.
