vishnukorde said:what exactly do you mean by "rotary wheel-like appendages" what does it mean that we can not use rotary wheel-like appendages?... then what can we use?
Rotary wheel-like appendages, also known as flagella, are used by certain microorganisms for movement. They act like a propeller, allowing the organism to swim through its environment.
No, not all organisms have rotary wheel-like appendages. They are mainly found in single-celled organisms such as bacteria and protozoa.
Rotary wheel-like appendages are made up of protein filaments that extend from the surface of the organism. These filaments rotate, creating a whiplike motion that propels the organism forward.
No, microorganisms have various methods of movement including cilia, which are shorter hair-like structures, and amoeboid movement, which involves the extension and retraction of pseudopodia.
Yes, besides movement, rotary wheel-like appendages can also be used for sensory purposes. Some bacteria use their flagella to detect and move towards food sources or away from harmful substances.
