Step 1: Understanding the functions of the cytoskeleton
The cytoskeleton is a network of protein filaments and tubules that provides structure, shape, and support to the cell. It also helps in intracellular transport and cell shape maintenance. However, intercellular transport is not a direct function of the cytoskeleton.
Step 2: Verifying the options
- Option (1) - The cytoskeleton helps in intracellular transport by acting as a highway for vesicles and organelles.
- Option (2) - The cytoskeleton provides mechanical support to the cell, contributing to its shape and strength.
- Option (3) - The cytoskeleton does not play a direct role in intercellular transport, which is carried out by other systems such as the circulatory system.
- Option (4) - The cytoskeleton maintains cell shape by providing structural support.
Thus, the correct answer is option (3) "Intercellular transport" because it is not a function of the cytoskeleton.
