Question

explain how different organisms carry out exchange of gases. give one example of each.

Answer 1

Answer:

In animals, gas exchange follows the same general pattern as in plants. Oxygen and carbon dioxide move by diffusion across moist membranes. In simple animals, the exchange occurs directly with the environment. ... Earthworms exchange oxygen and carbon dioxide directly through their skin.

Answer 2

Different organisms carry out the Exchange of gases in their body differently in the following ways

The process of gas exchange refers to respiration in organisms.

• Gas exchange across surface membranes is effective for organisms with diameters less than 1 mm.
• Every cell in the body of simple organisms, such as cnidarians and flatworms, is in close proximity to the external environment.
• Their cells stay moist, and gases diffuse quickly through direct diffusion.
• Simple multicellular organisms, such as green algae, have cells that are close to the environment, allowing for easy gas exchange.
• Animals and plants both follow the same gas exchange pattern.
• Diffusion transports oxygen and carbon dioxide across moist membranes.
• Earthworms exchange oxygen and carbon dioxide via their skin.
• unicellular organisms perform gas exchange through their body surface through the diffusion process. example: amoeba.
• plants perform gas exchange by diffusion through stomata and lenticels.
• aquatic animals perform gas exchange using their gills. example: fishes
• Terrestrial animals perform gas exchange by lungs by pressure variations. Examples: human beings.
