Question

1. what is cytoskeleton? what are some of its functions? 29. compare and contrast cilia and flagella. for both, select a human cell that has this feature, and describe the role for that cell.

Explanation:

1. The cytoskeleton is a network of protein filaments in the cell. It provides structural support, enables cell movement, and is involved in intracellular transport and cell - division.
2. Cilia are short, numerous hair - like structures, while flagella are long, fewer in number. Ciliated cells like those in the respiratory tract move mucus and trapped particles. Sperm cells have a flagellum for locomotion to reach the egg.

Answer:

1. The cytoskeleton is a network of protein filaments in the cell. Its functions include providing structural support, enabling cell movement, facilitating intracellular transport, and participating in cell - division.
2. Cilia are short and numerous; flagella are long and fewer. Ciliated cells in the respiratory tract move mucus and particles. Sperm cells have a flagellum for movement to fertilize the egg.
