Answer
The plants do not possess any respiratory system still plants respire. The various parts of the plants like leaves, roots, etc., carry out respiration independently. These parts take in oxygen from air in different manner and utilise it to obtain energy and give out $\mathrm{CO}_2$. The leaves of plants possess tiny pores on their surface which is called as stomata. The gaseous exchange during respiration takes place through their stomata.
