Plants conduct gas exchange in photosynthesis by bringing in carbon dioxide and releasing oxygen through openings calledMultiple choice question.

The openings through which plants conduct gas exchange in photosynthesis, bringing in carbon dioxide and releasing oxygen, are called stomata.

Explanation

Stomata are microscopic pores located primarily on the surfaces of leaves. They are surrounded by guard cells that open and close the stomatal pores, allowing for the exchange of gases. When stomata open, carbon dioxide enters the leaf for photosynthesis, and oxygen produced as a byproduct is released into the atmosphere. This process is crucial for plant respiration and overall ecological balance, making stomata essential for life on Earth.

In summary, the correct answer is stomata.
