To analyze:
Cytoskeleton within the cytoplasm was a recent discovery.
Introduction:
Recently discovered cytoskeleton provides support to the cell structure. Before discovery, scientists thought that cell organelles freely move into the cytoplasm.
Explanation of Solution
The discovery of cytoskeleton was recent because of technical limitations and scientific knowledge. Firstly, scientists thought that tubules were lying without a specific function. Second, microscopic and immune techniques were not well developed.
The cytosol is the main element of the cytoplasm. The cytoskeleton does not contain any essential biological molecule, but it performs a structural function in the cell.
The cytoskeleton is the same as a lipid bilayer, it helps to provide the interior structure of the cell membrane. A cell is always identified by its intracellular biological elements, which is responsible for shape changes. The cytoskeleton performs the function of shape changes.
Cytoskeleton facilitates the intracellular organelle movement and involves intracellular communication. It is formed by three types of protein filaments, actin, intermediate filaments, and microtubule.
Thus, the cytoskeleton is responsible for cell movement. It is made of intermediate filaments, microtubule, and, actin.
