The method of respiration which takes place in euglena is 

Key Points

• Euglena respires through the process of diffusion, where gases are exchanged directly through the cell membrane.
• The process of diffusion allows oxygen to enter and carbon dioxide to exit the cell, facilitating cellular respiration.
• This method of respiration is efficient for single-celled organisms like Euglena due to their small size and large surface area-to-volume ratio.
• Diffusion does not require specialized respiratory structures, making it ideal for simple organisms.
• Environmental factors such as the concentration of gases and temperature can influence the rate of diffusion in Euglena.

Additional Information

• Euglena is a genus of single-celled flagellate protists that are found in freshwater and saltwater environments.
• Besides diffusion, Euglena can also perform photosynthesis due to the presence of chloroplasts, allowing them to produce their own food.
• In addition to their unique method of respiration, Euglena can move using a whip-like structure called a flagellum, which propels them through the water.
