Flagellum (Flagellum, Pl. Flagella)

Flagellum (Flagellum, pl. flagella)

Flagellum (Flagellum, Plural Flagella) is a thin, long, flagella-like outgrowth of a cell surrounded by plasmalemma found in some cells (for example, sperm and a number of unicellular organisms). Flagella perform the function of moving these cells.

Flagella are thin, long, flagellum-like cell projections that are found in some microorganisms, such as sperm and single-celled organisms. They perform the function of cell movement.

Flagella consist of three main components: a rod filament, which is the main part of the flagellum and can be twisted into a spiral, 9 paired microtubules and a basal plate. Microtubules form a helical structure that enables the movement of the flagellum.

In sperm, flagella play an important role in the process of movement and fertilization. They ensure rapid movement of the sperm to the egg. In addition, flagella can serve to protect the cell from harmful substances and bacteria.

Single-celled organisms such as bacteria also have flagella that help them move through their environment. These flagella allow bacteria to move and also help them avoid predators and find food.

Thus, flagella are an important component of the cell and play an important role in its movement and survival.
