NEET BIOLOGY

Detailed explanation-1: -Flagella (singular = flagellum) are long, hair-like structures that extend from the plasma membrane and are used to move an entire cell, (for example, sperm, Euglena). When present, the cell has just one flagellum or a few flagella.

Detailed explanation-2: -flagellum, plural flagella, hairlike structure that acts primarily as an organelle of locomotion in the cells of many living organisms.

Detailed explanation-3: -Flagella are whip-like appendages that undulate to move cells. They are longer than cilia, but have similar internal structures made of microtubules. Prokaryotic and eukaryotic flagella differ greatly.

Detailed explanation-4: -Flagella. Some bacteria also have tail-like structures called flagella (Figure below). Flagella help bacteria move. As the flagella rotate, they spin the bacteria and propel them forward.

Detailed explanation-5: -How Do Cells Move? Cytoskeletal filaments provide the basis for cell movement. For instance, cilia and (eukaryotic) flagella move as a result of microtubules sliding along each other. In fact, cross sections of these tail-like cellular extensions show organized arrays of microtubules.
