Hey there!

Plants have no specialized organs for gas exchange. The are several reasons they can get along without them:

1. Every part of the plant takes care of its own gas exchange needs.

2. Roots, stems, and leaves respire at rates much lower than are characteristic of animals. 

3. The distance that gases must diffuse in even a large plant is not great. Each living cell in the plant is located close to the surface.

While obvious for leaves, it is also true for stems

4. Oxygen and carbon dioxide also pass through the cell wall and plasma membrane of the cell by diffusion.

Plants take in carbon dioxide and give out oxygen directly through pores in their leaves and other tender parts, so they don't need lungs or any other respiratory organ
