diffusion across their body surface (cell surface membrane)
Amoebas obtain oxygen and release carbon dioxide through diffusion. Oxygen from the surroundings enters the amoeba's cell membrane, while carbon dioxide diffuses out of the cell membrane into the environment. This process occurs due to concentration gradients.
The carbon dioxide gradient within an amoeba is maintained through cellular respiration and diffusion. As the amoeba metabolizes nutrients, it produces carbon dioxide, which accumulates in the cytoplasm. This concentration gradient allows carbon dioxide to diffuse out of the cell into the surrounding environment, where the concentration is lower. The continual uptake of oxygen for respiration helps to further sustain this gradient by keeping carbon dioxide levels within the amoeba in check.
stomata
lungs
The respiratory system exchanges oxygen and carbon dioxide in the lungs through the process of respiration. In the lungs, oxygen is taken in from the air we breathe and transferred into the bloodstream, while carbon dioxide is released from the bloodstream into the air we exhale.
They EXCHANGES GASES The Same Way As We Do. OXYGENEnters Their LUNGS And Exits Out As CARBON DIOXIDE.
Amoebas are small single-celled organisms with a large surface area-to-volume ratio, allowing for efficient gas exchange through their body surface by simple diffusion. This surface area contact with the environment facilitates the exchange of oxygen and carbon dioxide, enabling them to meet their metabolic needs.
The respiratory system exchanges oxygen and carbon dioxide with the air through the process of breathing. Oxygen is taken in through the lungs and carbon dioxide is expelled during exhalation. The exchange occurs in the alveoli, which are tiny air sacs in the lungs.
