Answer 2

The function of long tail-like projections streaming from a bacterium is mobility. (option 1)

• Flagella are tiny, hair-like structures that aid in a cell's movement.
• The Latin word "flagellum" is a whip.
• A cell is propelled through the liquid by the whip-like appearance of the flagella.
• Certain unique flagella are used by a select few organisms as sensory organs that can detect pH and temperature changes.
• The primary function of the flagellum, a motility organelle, is to promote movement and chemotaxis.
• Bacteria can be either polar (having one or more flagella at a single location) or peritrichous, and they can have one flagellum or several (several flagella all over the bacterium).
• Bacteria are divided into four types based on how many flagella they have: monotrichous (one flagellum), amphitrichous (one flagellum at each end), lophotrichous (many flagella in a tuft), and peritrichous (flagella distributed all over the cell except at the poles).

Hence, the function of long tail-like projections streaming from a bacterium is mobility.
