Gas exchange in Amoeba basically takes place across the whole body surface by diffusion. With their huge surface area which is relative to the volume, single celled animals can productively get oxygen and also remove carbon dioxide via diffusion across the surface.
have i helped u from this answer
my name is yash verma
They sort of hug then they exchange gases to help each other through exchanges at the mouth
Amoeba has no special organs for exchange of gases. It breathes due to diffusion through the surface.
how oxygen and carbon dioxide gases are exchanged between an amoeba and its surroundings.
Oxygen diffuses in and carbon dioxide diffuses out. respiratory processes in the cytoplasm is simple diffusion of carbon dioxide between the cytoplasm and the surrounding. water
By osmosis and diffusion
The entire surface of the amoeba is its respiratory surface. It is always wet because the amoeba lives in water, and oxygen continually diffuses in and carbon dioxide continually diffuses out.
Stomata is a tiny opening or pore, found mostly on the under-surface of a plant leaf. It is responsible for gaseous exchange between the leaves of plants and the environment.
Gas exchange occurs in the alveoli of the lungs.
large organisms need larger area to exchange more substances.but large organisms have small surface area to volume ratio.this means that the surface is not large enough to enable gases and nutrients at the fast rate needed to keep all the cells alive.thus large organisms need special exchange surfaces to provide the body with the nutrients and gaseous exchange they require.
Gills.
Small organisms, like a amoeba's, have large surface area : volume ratios which means the exchange can take place by diffusion through the cell wall, the same as any other single celled organsism.
For respiration - the taking in of oxygen and removal of carbon dioxide - the gases simply diffuse through the whole of amoeba's permeable surface. Soluble nitrogen-containing wastes, produced by the amoeba's chemical activities are excreted in the same way.As you may know, the amoeba has no special respiratory organs and norespiratory pigments, but there is a free exchange of gases by diffusionor osmosis through the general body surface (plasmalemma), which ispermeable to the gases dissolved in water.
exchange gases through their moist body surface ?
diffusion across their body surface (cell surface membrane)
The respiration system adopts to the surface area to volume ratio to help the exchange of gases.
Root Surface
Stomata that can help plants to exchange gases.
They respire with the help of a porous cell membrane around them.
Through stomata and lenticells
During respiration the exchange of gases takes place through the walls of the alveoli. From there, the oxygen is taken by the blood to the body tissues.
the lungs
Like all fish- through their gills.
