stomata
The air sacks which provide the surface through which gas exchange occurs are called alveoli.
In prawns, gas exchange occurs through specialized gill structures. These gills are rich in blood vessels and allow for the exchange of oxygen and carbon dioxide between the prawn's respiratory system and the surrounding water. The thin, permeable surface of the gills facilitates efficient gas exchange.
Fungi exchange gases primarily through structures called hyphae, which are thin, thread-like filaments that make up their mycelium. Gas exchange occurs via diffusion through the cell walls of these hyphae, allowing oxygen to enter and carbon dioxide to exit. Additionally, some fungi may utilize specialized structures, like fruiting bodies, to facilitate gas exchange more efficiently. Overall, this process is essential for their respiration and metabolic functions.
The process is called gas exchange, and it mainly occurs through small openings called stomata on the leaves of plants. These stomata open and close to regulate the exchange of gases like oxygen, carbon dioxide, and water vapor between the plant and its surroundings.
The small sac-like structures in the lungs are called alveoli. This is where the exchange of oxygen and carbon dioxide occurs with the bloodstream, a process known as gas exchange. Oxygen diffuses from the alveoli into the bloodstream, while carbon dioxide moves from the bloodstream into the alveoli to be exhaled.
The structure in the epidermis that gaseous exchange occurs in plants is through the stomata. A stomata is a tiny opening or pore in the epidermis.

Oxygen enters your nose,then goes through the trachea,to the bronchi,and last to your lungs.
Algae exchange gases with the environment primarily through a process called diffusion. Carbon dioxide (CO2) from the surrounding water enters the algal cells, while oxygen (O2), produced during photosynthesis, diffuses out into the water. This exchange occurs directly through the cell membranes, as algae do not have specialized gas exchange structures like those found in higher plants. The efficiency of this process is enhanced by the large surface area of algal cells and their aquatic environment.
The dermal branchia is an extension of the body cavity through with oxygen consumption occurs--(gas exchange) The pedicellariae are picher or jawlike structures that clean debris off of seastar.
The gas occurs by simple diffusion through the cells.
