Question

The cytoskeleton has several primary functions. the first and most obvious is it acts as an interior skeleton that supports the rest of the cell. what is another function of the cytoskeleton?

Answer 1

Answer

Discovery

              In 1928 Kotlzuf observed a network of fibers extended through out the cytoplasm with hep of light microscope. It was confirmed by Cohen when studying it under electron microscope in 1972.

Structure

            It is a network of protein fibers that extend through out the cytoplasm. It is also called as skeleton of cytoplasm.  

Composition

            It is composed of different types of proteins, like actin, troponin, myosin etc.  

Types

         Cytoskeleton is of three types, these are

1. Micofilaments

2. Microtubules

3. Intermediate filaments.

Function

1. Cyclosis

              It is the streaming movement of cytoplasm which is controlled by cytoskeleton. It help in the transport of different organelles like ribosome and mitochondria to those area where they are needed.

2. Amoeboid movement

             Cytoskeleton help in amoeboid movement through which amoeba move towards sunlight or any other thing needed as food.

3. Maintain cell shape

            Cytoskeleton help in maintaining shape of cell.

4. Spindle fibers

          Cytoskeleton also help in the assembly and disassembly of spindle fibers during cell division.
