Answer:
- plants respiratory systems=>
Roots, stems, and leaves of plants exchange gases for respiration separately. As we all know, leaves have tiny pores called stomata, which is used for the exchange of gases. The oxygen, taken in through stomata is used by cells in the leaves to break down glucose into carbon dioxide and water.
2. animals respiratory systems=>Some animals such as amphibians are able to exchange gases through their moist skin. Fish have gills while mammals, birds, and reptiles have lungs. Your respiratory system is made of your nose and mouth, a tube called the pharynx, another tube called the trachea, and your lungs.
