Statement A accurately describes respiration in plants.
In plant, gaseous exchange occurs with atmosphere during two process namely respiration and photosynthesis. The organ of respiration in plant is called as stomata. They are minor pore like structure located on the surface of the leaves.
The oxygen which is present in the atmosphere enters the plant through the leaves and it is sent to other parts of the plant through diffusion mechanism. As the respiration process is completed, the carbon dioxide which is formed as the end product of the process, is exhaled out of the plant through the stomata.
