Which of the following functions is carried out by cytoskeleton in a cell ?
Nuclear division
Protein synthesis
Motility
Transportation
Answers (1)
The correct answer is Option 3) Motility.
The cytoskeleton is a network of protein filaments found in the cytoplasm of cells. It plays a crucial role in providing structural support, maintaining cell shape, and facilitating various cellular processes. One of the key functions of the cytoskeleton is cell motility, which includes the movement of cells themselves and the movement of cellular components within the cell.
The cytoskeleton is responsible for the movement of cells through processes such as amoeboid movement, ciliary/flagellar movement, and muscle contraction. It provides the necessary structure and organization for these movements to occur.
While nuclear division (Option 1) is primarily regulated by the spindle apparatus during mitosis and meiosis and protein synthesis (Option 2) is carried out by ribosomes, the cytoskeleton is not directly involved in these specific processes.
Transportation (Option 4) can involve the cytoskeleton indirectly, as it provides tracks or highways for intracellular transport, but it is not the primary function of the cytoskeleton. The cytoskeleton's primary role in transportation is to help maintain the cellular architecture and provide support for the transport systems.
Therefore, the correct function carried out by the cytoskeleton in a cell is Option 3) Motility.
