Gaseous exchange occurs through the following structures in some organisms except

Gaseous exchange refers to the process of exchanging gases, such as oxygen and carbon dioxide, between an organism and its environment. Spiracles and tracheae are respiratory structures found in insects and some other arthropods that allow for gaseous exchange. Alveoli and lungs are respiratory structures found in mammals that allow for the exchange of gases between the body and the environment. Stomata and lenticels are structures found in plants that allow for gaseous exchange. However, chloroplasts and plastids are not involved in gaseous exchange. They are organelles found in plant cells that are involved in photosynthesis and storage of nutrients. Therefore, the correct answer is "chloroplast and plastids".
