How does air get inside pumpkins?

Also, is the air composed of the same gases as atmospheric air?

All plants take in air via respiration, and they do create air sacs which are normally composed of air with a higher-than-normal level of carbon dioxide. Air travels through and between plant cells in very minute amounts. They do so by absorbing air through lenticles, small extrusions of respiratory tissue along plant stems (They are larger and more visble in fruit trees such as Apple and Cherry, which have prominent horizontal lenticles up the trunk). These lenticles help provide oxygen to the plants for growth.

Hope this helps :)
