Which part of the plant absorbs atmospheric carbon dioxide for photosynthesis?

Stomata

The correct answer is Option (3) –Stomata

Stomata are tiny pores primarily located on the surface of leaves (and sometimes on stems) of plants. These pores are surrounded by specialized cells called guard cells. Stomata play a crucial role in gas exchange, allowing plants to take in carbon dioxide (CO₂) from the atmosphere for photosynthesis and release oxygen (O₂) as a byproduct. During photosynthesis, carbon dioxide diffuses into the leaf through the stomata and reaches the chloroplasts, where it is used in the process of photosynthesis to produce glucose and other organic molecules.
