Which part of the plant takes in carbon dioxide from the air for photosynthesis?

The part of the plant that takes in carbon dioxide from the air for photosynthesis is the leaf. More specifically, this process occurs in the stomata, which are small openings or pores in the leaf surface, primarily on the underside. Here's a step-by-step explanation:

1. Carbon dioxide enters the plant through tiny openings called stomata, which are mostly found on the underside of leaves.

2. The stomata open and close to allow the intake of carbon dioxide and the release of oxygen.

3. The carbon dioxide that enters the stomata moves into the interior of the leaf.

4. Inside the leaf, in the chloroplasts of the plant cells, the process of photosynthesis takes place.

5. During photosynthesis, the plant uses sunlight to convert the absorbed carbon dioxide and water into glucose (a type of sugar that provides energy for the plant) and oxygen.

6. The oxygen is then released back into the air through the stomata.
