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

Options

A. root hair
B. stomata
C. leaf veins
D. sepals

Answer

**Step-by-Step Solution:**

1. **Understanding Photosynthesis**: Photosynthesis is the process by which plants prepare their food using light, carbon dioxide, and water. This process occurs primarily in the presence of sunlight.

2. **Identifying the Inputs**: The main inputs for photosynthesis are carbon dioxide (from the air), water (from the soil), and light (from the sun).

3. **Role of Leaves**: The leaves are the primary sites where photosynthesis occurs. They contain chlorophyll, which captures light energy.

4. **Gas Exchange**: For photosynthesis to take place, carbon dioxide needs to enter the plant. This gas exchange occurs through tiny openings on the leaf surfaces.

5. **Stomata**: The tiny openings on the leaf surfaces are called stomata. These stomata allow carbon dioxide from the air to enter the leaf and oxygen to exit.

6. **Conclusion**: Therefore, the part of the plant that gets carbon dioxide from the air during photosynthesis is the stomata located on the leaves.

**Final Answer**: The stomata on the leaves of the plant get carbon dioxide from the air during photosynthesis.
