Features of gas exchange surfaces
- Have a large surface area relative to the volume of the organism.
- They are thin, so have a short diffusion pathway.
- They have a moist surface where gases can dissolve first before they diffuse in our out.
- They are able to maintain the diffusion gradient down which the gases can diffuse.

Why all gaseous exchange surfaces moist?
All gaseous exchange surfaces are moist to facilitate the diffusion of gases. Water vapor present in the moisture creates a concentration gradient, allowing oxygen and carbon dioxide to dissolve and diffuse more easily across cell membranes. Additionally, moisture helps maintain the structural integrity of the exchange surfaces, preventing them from drying out and ensuring efficient gas exchange. This is especially crucial in organisms like humans and plants, where respiration and photosynthesis rely on effective gas exchange.
How does gaseous exchange take place in the lower plants?
In lower plants such as mosses and liverworts, gaseous exchange occurs through simple diffusion across the cell membranes. These plants lack specialized structures like stomata found in higher plants, so gases enter and exit the plant cells directly through their surfaces. This process is limited by the surface area available for exchange, making lower plants reliant on moist environments for efficient gaseous exchange.

Why are the gaseous exchange surfaces of most terrestrialland livinganimals inside their bodies?
Gaseous exchange surfaces inside the body of terrestrial animals help to protect the delicate respiratory membranes from drying out and damage. This internal arrangement also helps to regulate gas exchange and maintain proper moisture levels, especially in dry environments. Additionally, it provides a more controlled and efficient system for exchanging gases such as oxygen and carbon dioxide with the bloodstream.
Where is the site for gaseous exchange?
The site for gaseous exchange is the lungs. Carbon dioxide is exhaled and is substituted for oxygen which is inhaled.
What exchange takes place in the lungs?
gaseous exchange - in the alveolis
Where in the lungs does gaseous exchange take place?
alveoli is the site for gaseous exchange. They are the air filled sacs where carbon dioxide and oxygen is exchanged
