Bacterial flagella impart motility to the cell by

Explanation

Bacterial flagella are whip-like structures that are found on the surface of bacteria and help in cell motility. This question is asking how bacterial flagella impart motility to the cell. The options given are undulating movement, rotatory movement, gliding movement, swaying movement, and looping movement. Undulating movement refers to a wavelike motion, rotatory movement refers to rotation, swaying movement refers to swinging from side to side, and looping movement refers to moving in loops. The correct answer to this question is C, gliding movement. Bacterial flagella move by a mechanism called rotary motion, but this is not how they impart motility to the cell. Rather, they help the cell move by a process called gliding movement. This is a type of movement where the cell moves smoothly over a surface without the use of flagella. It is important to understand the various types of bacterial movement, as this can help in identifying different types of bacteria. For example, some bacteria move by flagella, while others use a type of gliding movement, and some bacteria do not move at all. In conclusion, bacterial flagella impart motility to the cell by gliding movement. It is important to understand the different types of bacterial movement to identify different types of bacteria.
